– “active users” (i.e. those with rep): about 4900, so that’s about 2200 more in a year
– 55 users are at or above 10k, compared to 18 a year ago
– there have been about 23 240 questions asked in total, so that’s about 12 200 more than a year ago (i.e. the average is roughly stable, around 11 500/year). Most don’t get as much votes as in the early days, but it’s still possible to ask highly appreciated ones, this recent one got 37 upvotes in 15 hours.
– it’s fair to say some areas of math are still vastly under-represented, especially dynamical systems broadly speaking, (a few new senior users would probably add much-needed traction there…)
So overall, a great past year, hoping for even more interesting stuff in the next one!
And to add a few words on little brother math.stackexchange.com who is now about 1 year and 2 months old, it is doing fantastic too: about 22 480 questions asked, many excellent contributors (32 of them above 10k) including Arturo Magidin (74k, 6 gold), Qiaochu Yuan (57k, 2 gold) and Bill Dubuque (47k, 3 gold).
