The claim was "actually been declining" which isn't supported by the
data. It's less than the peak, but you don't call home sales in
decline at all times that it is less than its all time peak.

That looks like a decline to me. The peak was about 8 months ago and
every month since has been lower than the previous.

That ones less clear, I guess. According to that maybe the number of
daily edits has leveled off after a recent decline. Then again, it
might have just been an anomaly in the June/July area where the
relatively big dropoff took place. I think time will tell on that
one.
Of course this all assumes these charts actually reflect correct data,
which I haven't really looked into at all. How were deleted articles
handled? How was the selection of the sample chosen? Isn't there a
sort of survivorship bias in that selection?
