PS. This story was triggered by Fastily's retirement. He has 46000 edits on enwiki, and only about 620 editors have reached that plateau. Of these, 90% are still active. So such retirements are relatively rare. Personally, I hope he decides to come back after taking some time to relax and recharge. It seems to be the case that many such declared retirements aren't really permanent.
