1）据venturebeat报道，Facebook发言人日前表示，Facebook将改变统计平台活跃用户的算法，Facebook应用的实际流量不会发生变化，但新的算法将更加精确和透明，此举有可能降低人们原来对MAU的价值判断。

知情人透露，由于算法发生变化，Zynga等社交游戏公司的MAU可能比原来更少，但降幅应该低于20%。

据AppData数据显示，Zynga目前MAU是2.63亿，假设采用新算法后Zynga游戏MAU下降11%以上，那么该公司的MAU就有可能低于其7月份IPO文件所称的2.32亿，这种情况意味着Zynga有可能面临失去这一领域的绝对优势。

2）Namco Bandai日前宣布将在DeNA旗下的社交平台发布两款热门游戏，一是已问世16年的Tales系列纸牌RPG游戏《Tales of Kizna》，该游戏在掌机平台已推出15个不同版本，拥有100多个角色。玩家的任务是通过“混合”卡片，建立独特的军队，也可以加入公会与更强大的敌人决斗。

二是偶像养成游戏《The Idolmaster》（游戏邦注：原版游戏于2005年发布），它同时也是该公司的首款“社交”偶像养成游戏。玩家在游戏中要扮演制作人角色，从原版游戏中的100个角色中挑选出“明日之星”，最终打造一个“顶级偶像军团”。

3）Facebook页面分析公司PageLever日前发布数据指出，生命周期最短的Facebook贴子只会在页面存在11至13小时，生命周期最长的贴子可能存在50小时（游戏邦注：这里的生命周期指贴子发布后，可被其他用户或粉丝所看到的曝光时间长度）。

需注意的是，PageLever仅采样了20个Facebook贴子的数据，但这些贴子均来自粉丝数据超过200万的页面（表明这些页面的用户参与度更高），由此不难推测粉丝数量更少的页面所发布的贴子生命周期还会更短。

除了使用PageLever的分析工具，用户还可以通过查看Like和评论数量判断是否需要重新发贴，以延长贴子的生命周期。一般来说，Likes数量比评论更多，所以更容易判断贴子的活跃指数。假如Like数量在一小时内迅速下降，用户就需要重新发贴。

4）The Sociable最新报告指出，Google+用户点击最多的社交网站+1点击量并非Google+而是Facebook，后者在Google+主页收获了约4.4万次+1点击量，比Google+多1000次。

值得注意的是，从9月25日The Sociable开始跟踪数据时，Google+主页的+1点击量数量几乎没有变化，而Facebook却已从原来的3.6万增长至目前的4.4万次+1点击量。

The Sociable称他们还使用了Google+ Chrome扩展调查数据，发现Twitter的+1点击量也在同一时期从原来的1.2万增长至1.4万。

5）俄罗斯第二大社交网站Odnoklassniki（游戏邦注：其影响力仅次于Vkontakte，归属于Mail.Ru Group，据comScore数据显示，Facebook在俄罗斯市场份额从未超过5%，也就是每月访问用户不超过500万）目前每月访问用户为2500万至2600万，在日前宣布网站添加了由以色列公司face.com所提供的新面部识别功能（face.com之前已向Facebook提供了该技术）。

这两项新功能包括面部检测和面部识别系统，前者可用于检测照片中的人数，以便用户对其贴标签；后者则可通过标签识别许多人物面孔。

6）在本周MAU增长最快的新晋Facebook游戏榜单（MAU介于10万至100万）上，《3D Slots》（MAU为78万）位列第一，《Spa Life》（MAU为22.3万）和《Heroes of Neverwinter》（MAU为19万）分别占据第二和第三席位。

第四名是《Serf Wars》（MAU为27万），该游戏于六个月前进入公开测试，最近用户小有增长。

Facebook engagement benefits(from Online PhD)

1）Facebook changes how it tracks users, raising questions about true audience numbers (exclusive)

Matthew Lynley

Zynga may be losing some ground after spending years completely dominating the Facebook social gaming market.

Facebook today announced that it is changing the way it counts the number of active users who access an application on its site, a move that will lower perceived values of monthly active users. The actual traffic to Facebook apps has not changed, but the new calculations should be more precise and transparent, a Facebook spokesperson told VentureBeat.

One of the sites affected is AppData, which tracks an app’s monthly active users and is widely used as a metric for gauging success of some social app companies.

With the new changes, Zynga’s (and other social app companies’) recorded monthly active users — as measured by Facebook’s metrics — could fall. Sources familiar with the situation told VentureBeat that the drop would be less than 20 percent. AppData currently reports Zynga has 263 million monthly active users.

A drop of 11 percent or more would bring the company below its own reported number of monthly active users, 232 million, which the company reported when it filed  to go public in July.

(Zynga has not updated that number since then.) That would imply that Zynga has lost ground to social gaming companies like Electronic Arts and Wooga. Those companies are nowhere near Zynga in terms of users but are still top-ten developers, and have been slowly making inroads in social games.

“We support Facebook’s decision to change the way it measures the number of active users of its applications as it more accurately portrays the number of people who play Zynga games,” a Zynga spokesperson told VentureBeat. “As noted in our S-1 filing, we measure our player number on Facebook by how many people access our games and we are pleased that Facebook, and therefore AppData, will accurately reflect that number.”

With an IPO in the works, any perceived slow-down in the company’s growth could diminish its perceived value to potential public investors. Zynga is the most profitable high-profile company that has filed to go public this year and expectations are extremely high for the company now that it has hinted at plans to break away from Facebook. (It’s worth noting that VentureBeat’s Dean Takahashi had a story earlier that throws a little bit of skepticism on the company’s accounting practices.)（source:venturebeat）

2）Namco Bandai Brings “Tales” And “The Idolmaster” Series To Mobage [Social Games]

by Dr. Serkan Toto

Nice win for DeNA today: partner Namco Bandai today announced [PDF] that it will bring two of its hit video game series to Mobage.

The first game is the far more important one: “Tales Of Kizna” is the first social game in the 16-year old “Tales” series of RPGS. Kizna is a card-based RPG that features over 100 characters that appeared in 15 previous “Tales” games on consoles.

Namco Bandai says that players will be able to build unique teams by “mixing” cards. Users can create or join guilds and battle large enemies (or other guilds) together.

“The Idolmaster” is Namco Bandai’s contribution to the idol-raising genre. Games like this are a dime a dozen in Mobage and GREE, but this game has the advantage of being part of a well-known series in the genre (the first Idolmaster game was released in arcades in 2005). It’s also the first “social” Idolmaster.

Players take on the role of a producer and get to choose between a total of 100 “idols” (stars) who appeared in previous games. The goal is to make it to eventually produce a “top idol unit”. Genre-wise, this will be the first Idolmaster card battle game (it has no title yet).

Namco Bandai says both titles will hit Mobage next month. The company recently launched a joint venture with DeNA, BDNA.（source:serkantoto）

3）The Average Facebook Post Lives 22 Hours And 51 Minutes

by Brian Carter

Your first goal with each post from your business Facebook page is to be seen by fans. But every post has a limited lifespan.

During that time, your fans see the post in their news feed and may like or comment.

But after a certain point, Facebook stops showing the post in their news feed.

If you knew the average lifespan of your posts, you could post again right when the previous posts died off. Your page would always have a live post out there for fans. You’d be maximizing your possible exposure.

How Often Should You Post?

The changes to the news feed emphasize recency by blending top stories and recent stories.

There’s been talk about whether pages need to post more often: Should the typical recommendation to post once a day shift to posting two or three times per day?

The chart above, using data from the advanced Facebook page analytics company PageLever, shows that for pages with large fan bases, the shortest post lifespan was 11 to 13 hours. The longest was 50 hours, which was over a weekend.

Caveats For This Study

This data comes from only 20 posts — an incredibly small sample size — but the posts are from pages with more than 2 million fans each, representing a lot of engagement.
In the Facebook application programming interface, comments have a time stamp, but likes don’t — they time stamp likes in PageLever. Impressions are less reliable, so stick with the middle column for data

It’s possible that since the average page has fewer fans than these sample pages, they’ll get less engagement and their post lifespan will be shorter.
Read more details in the PageLever post.

Manually Discover Your Own Post Lifespan

Even without PageLever, you can check your own page’s typical post lifespan. Just check your post every hour and count its likes and comments.

Impressions are updated irregularly, so they’re not as reliable a way to check. Likes are much more reliable, and tend to happen in larger numbers than comments. So likes are the best metric to watch for post-die-off.

Once the likes per hour drop off dramatically, it’s time to post again. The only thing is, it’s a drag to do this manually, around the clock.（source:allfacebook）

4）Facebook Gets More +1 Clicks Than Google Plus

by David Cohen

Google Plus users have clicked the +1 button for the homepage of which social network most?

If you guessed Google Plus, you guessed incorrectly.

The Sociable reported that the Facebook homepage was the subject of around 44,000 clicks of the +1 button on Google Plus, which is 1,000 more than the Google Plus homepage gets.

What’s more, the total for the Google Plus homepage has barely moved since The Sociable began tracking it Sept. 25, while Facebook’s total has risen from around 36,000 on that date.

The Sociable said it used Google’s +1 Chrome extension to obtain the figures, adding that Twitter has seen modest growth, as well, at some 14,000 +1 clicks currently versus 12,000 September 25.

Readers: Have you been tracking the competition between Facebook and Google Plus, or did you just say, “What competition?”（source:allfacebook）

5）Key Russian social network adds facial recognition to photos

by Mike Butcher

Odnoklassniki, is the second largest social network in Russia, behind Vkontakte, and is part of the recently floated Mail.Ru Group. Facebook’s market share in Russia has never passed 5%, according to ComScore (or 5 million people a month). Odnoklassniki has 25-26 million visitors a month. That gives some context to the news today that Odnoklassniki today launches a new face detection feature powered by Israeli-based startup face.com, which already provides its technology to Facebook.

The two new features are: face detection and facial recognition. Face detection makes it possible to automatically determine the number of people in a photo and provide users with a an easier tool for tagging.

Facial recognition comes after the platform has been taught to recognise lots of faces via tags (clearly), eventually reducing tagging to a simple «yes» or «no» question.

Despite this move, Odnoklassniki says they are “seriously considering their users privacy.” Let’s hope so. It says private photo albums will remain un-trawled by Face.com’s app, and users will also be able to prevent the system from tagging them by changing their personal settings.（source:techcrunch）

6）3D Slots, Spa Life Top This Week’s List of Emerging Facebook Games

AJ Glasser

Social Games 3D Slots stays on top in this week’s list of emerging Facebook games, while Spa Life and Heroes of Neverwinter round out the top three.

At No.4, we see Serf Wars beginning a growth spurt as the title “officially” launches on Facebook. We got an early look at the game six months ago after the game launched in open beta.

Just a reminder that our list of emerging Facebook game is defined by growth among titles between 100,000 and 1 million monthly active users. We use this as an arbitrary set of parameters to determine the health of a game with the idea that it’s “made it” when it breaks 1 million.（source:insidesocialgames）

7）Facebook Engagement Benefits Students: Infographic

by Jackie Cohen

Whether Facebook benefits students depends on how they use it. Those who focus on engaging with other people on the social network come out ahead.

College students spend an average of 100 minutes a day on Facebook, logging on six times daily;

Some 82 percent of colleges have Facebook pages for outreach to prospective students, but

Three quarters of the kids applying for college think the schools need to provide a private community for incoming students. （source:allfacebook）
