The latest blog post has a graph of raised flags:

enter image description here

You'd expect it to be relatively "smooth" but there's a drop of about 3,000 flags in September 2012 compared to August 2012, and then right after it goes up by 7,000 flags in October. What happened?

  • Perhaps people were too busy preparing for armageddon? Besides, why not ask why were flags up from September to October?.

  • I wondered that too when I saw it... The only thing that comes to mind was that the new review badges were introduced in September, but it seems to me like that would have caused a bump, not a drop?

  • Perhaps there was some maintenance run on the server or other software bug that caused September's votes to be counted in October which would explain both irregularities. Mar 9, 2013 at 7:37

    August through December '12 is the time when new review system has been deployed, settled and widely experimented with, I would look for correlations with that. As an example, in November I've been raising helpful flags from Late Answers queue at a crazy rate about 50/day, that never been the case to me before and after that

    Looking through my own flagging history, there was indeed a drop in my own flagging pattern (from around 11 pages in August to only around 4 pages of flags in September). Can't remember what the cause was, but most probably because I dislike the interface of review queue since it slows down my flagging speed. (I stopped flagging in November, and resume flagging in December when I got 10k).

Personally, I don't think that the drop is anything but an outlier. On this graph, it looks like a rather major drop -- till you notice that the graph is truncated. It's an ~8% drop, nothing big.

The rise after that, however, probably can be explained by the introduction of the new review queue.
