Looking at the stats on the area51 page for music.SE, I first had the impression it was doing pretty well. Today I found out that the Startup Business SE was closed, looking at it's stats, it has very similar results to music.SE, even a little better in some areas.
Music.SE (972 days) | Startup business (1176 days) questions per day: 3.9 4.9 % answered: 99 98 avid users: 377 749 total users: 5,378 18,139 answer ratio: 2.8 3.1 visits per day: 7,317 2,778
Yes, we do get much more visits, but we're also a much smaller community. If we multiply the number of users by the number of visits, Music.SE gets 39,350,826 user.visits and Startup business SE get 50,390,142 user.visits; still better than Music.SE. Don't ask me why I invented such a metric, I just think if you need to combine the number of visits and the number of users in a single metric it makes more sense to multiply them rather than add them together. Anyway, should we be worried about the future of Music.SE?
There are plenty of question about how to improve this site, so please let's just keep it about the results on area51 and the fate of Music.SE.
