Regular readers will notice that this week’s list of the fastest-growing apps on Facebook by daily active users is the first of our lists to show up in a week. That’s because Facebook is currently almost two weeks behind in updating its all-important monthly active user stats, apparently due to a bug.

But DAU stats are updating, so we can resume at least partial service — meanwhile hoping, along with many developers, that Facebook resumes regular service soon. Here’s our AppData top 20 list:

The top gainer over the past two weeks is MindJolt Games, Facebook’s largest game portal. Following its recent acquisition by a group including several former MySpace execs, MindJolt’s total user count has become more volatile, but it appears that the new management team’s strategies for bringing back the users that it does have more often are successful.

We’ll cover the rest of the games this morning over at Inside Social Games. The next two on the list, then, are Facebook (for iPhone) and Facebook for BlackBerry. The two mobile apps regularly appear on our DAU list; the only thing strange about their appearance is that Mobile, the catch-all app for other phones, hasn’t gained much in a while. Further down, the newer HTC Sense mobile app is coming up fairly quickly, having just topped a million DAU.

Causes looks like it made a significant gain, but don’t be fooled — click through to its AppData chart and you’ll see that it’s down several hundred thousand DAU for the month. However, variations in its DAU have usually happened fairly independently of MAU in the past, the latter stat usually not changing much.

Finally, there’s an app that we haven’t seen mentioned for quite a while on our list, down at number 14. Extended Info, which adds fields to a user’s interests, hasn’t actually gained as many new DAU as you’re seeing. But the sudden spike (taking place in just the last two days) suggests that the app, which was acquired by Sidestep in 2007, has started an advertising campaign.
