@MaurycyZarzycki Once, I would have said most. Now... not so sure.
@SimonGill I think its the signal-to-noise ratio. And the fact that SO is no longer a labor of love from most of the members like RPG.SE or a lot of the smaller communities. It sees more business use, and the incidence of people taking but not giving back is a lot higher now.
Also, people ask a lot of stupid questions. And with that tide, downvoting doesn't really help. So people get disenchanted and discouraged. I really hope that doesn't happen here... but with the subject matter, I don't think we're in danger of that.
But you see a lot of the same on Arqade, unfortunately.
