Bing‘s social sidebar integration came in at No. 2 with an additional million MAU. No. 3 Washington Post Social Reader continues to enjoy a resurgence this month.

Facebook’s own Power Editor, which is an ad creation tool for advanced advertisers, made an appearance on our this week, which could be related to the Ads API being updated to include new News Feed metrics. Typically Facebook doesn’t report figures for its own apps, so the 869,562-user increase was not actually the result of new users. That is likely the total MAU for the tool.

Similarly, No. 13 Windows Live Mail, which is a Facebook integration for Microsoft’s desktop email client, does not typically report MAU data, so today’s spike is an anomaly.

No. 5 Zoosk, No. 6 Instagram, No. 7 Scribd, No. 8 Causes and No. 10 BranchOut are likely growing due to their integrations with Facebook Open Graph, which allows structured publishing to Timeline, Ticker and News Feed.
