I've answered a few questions so far in my short time using chess.SE, and I've been flattered that a number of them have been accepted rather quickly. I do think these were pretty good answers, probably worthy of being accepted; that's why I posted them, after all. However, I've noticed that this quick acceptance is a trend occurring with many of the questions getting asked, and I think that those active users who are asking a lot of questions (and thus doing a great service toward growing the site!) might be able to do a further service by waiting a spell before actually accepting answers. (Sometimes it might make no sense to wait, but I'm speaking generally here.)
Once a question is marked as having an accepted answer, I think folks will be somewhat less likely to post additional answers. Maybe it only makes it a little less likely, but my point is this: we're hoping to grow the site right now, and as new users come by, the more "open" questions around, the more likely they are to start joining the conversation. Moreover, aside from the growth aspect, accepting an answer too quickly (even one you think is nice), might just lead you to missing out on some other great, better answer, say from a slightly different perspective no one else has thought of.
So my suggestion to superstar question askers: once you've posted a question, maybe hold off 24 hours before clicking "accept." This will encourage more answers from more sources. I also think this could lead to more voting, as users will be keen to support one option over others (or support them all!). It's great that you want to put a further stamp on nice answers beyond voting them up, and it's a good thing to do so, but there's really no rush. It'll still be there for accepting tomorrow, and maybe some better alternative will be too. :-)
