February 16, 2010Wikimedia has a users RPE of 30mil.
“Wikimedia Foundation currently employs 14 technical people (not all of whom are developers). At 400 million readers/month (as of February 2010), that’s about 1 developer per 30 million users. Accounting for open source developers probably doesn’t change that ratio by an order of magnitude.” (not exactly apples to apples, but still interesting)1. (Aside programming, rpe, scale)
