Bjarne D├Ącker, who has been tracking download and web site statistics on erlang.org for years, just produced a new graphic.

Visits to http://www.erlang.org up to March 2010

For years, the erlang.org graph has been nicely exponential. This latest peak seems to break the pattern. It will be interesting to see what follows.

(Update: Looking closer at the graph, it appears to stretch as far as to March 2010. I changed the caption, but left the URL unchanged.)

(Update 2: Closer inspection suggests that this is indeed measurement error. Google analytics, which also takes mirrors into account, reports a steady, but decidedly less dramatic, rise. The number of visitors to erlang.org is now at ca 80,000/month, up from ca 57,000/month in September 2008.)
