Comment(by karsten):

 Replying to [ticket:3822 arma]:
 > Perhaps we should go through and take out the data points for the most
 extreme dips? Right now we show usage spikes that are false positives,
 which distract from the usage spikes that actually reflect an increase in
 users.

 Cutting off values based on the fraction is going to be difficult.  The
 analysis in #3338 only looked at 2011, and from those data it looks like
 excluding everything with a fraction of 10% or less leads to "better"
 results.  But before 2011, we had even fewer directories reporting
 statistics, and we had fine results, too.  See the attached graph.

 I wonder if there are better ways to smoothen the graph.  Like, for every
 day X, take the median of X-1, X, and X+1 and plot that.
