Adding more editors “is one of our top priorities for the year,” says Howie Fung…aims to increase the number of editors across all languages of Wikipedia to 95,000 from 81,450 by June of next year.
From http://stats.wikimedia.org/EN/TablesWikipediaZZ.htm using the >5
edits a month metric used in WMF docs:
1. July 2012: 76,400 2. June 2012: 74,402 3. May 2012: 76,956 4. April 2012: 75,141 5. March 2012; 76,274
The high water mark, incidentally, seems to have been March 2007 with 90,618 editors >5 edits that month. So we have been shrinking ~2.8k editors a year ((91 - 77) / (2012 - 2007)). In retrospect, my 75% prediction that this priority would not be achieved (http://predictionbook.com/predictions/3241) was ludicrously optimistic, given that the 95k editor mark has *never* been reached.
