I The following is based on what various other people have said, either about how others behave, or about how they themselves behave. It doesn't apply to me so I'm offering it as "what I heard the crowd say". Value appropriately :-).
The list is seen by people all around the world - I'm in NZ and my daytime is Europe's night time. USA is 6 to 9 hours ahead of me in time and 1 day behind me in date. A question accepted in 1 or 3 or 6 or 12 hours may happen before people like me ever get to see it.
If you accept the 1st answer given within about an hour of asking you will sometimes discourage people who care about reputation. Unless the answer utterly cries out to you as the ultimate answer to every aspect of what you wanted to know, it's probably best to wait a day or so to see what comes. Longer if a lively Q&A gets going as is sometimes the case.
About nobody is likely to mind waiting a day of few for their pearl of wisdom to be accepted, so as long as you do accept and answer 'after a while' all should be well.
Note that on other SE sites and presumably this one, you can un-accept an answer and accept another one instead. This happens occasionally. That's not something that you want to make a habit of as, amongst other things, it shows as a points deduction on a user's total, which can be disturbing when they do not understand why.
