So there's a question you have the answer to and you post it as an answer.
A short time later (maybe even seconds), a second potential solution comes to mind that's a different way of solving the issue. What do you do? Post it as a second answer or edit the first answer to make it even longer and encompass both answers?
I lean towards posting a second answer, but I note that there are no badges encouraging this. I expected there would be something like "two answers to the same question, both with a score of at least +1" (to stop answer spamming), but I can't see one.
I feel multiple answers should be encouraged as often the second answer will be better than the first. Also of course in this realm there are often multiple solutions to a problem and none is "right".
