Let's say that there is a question which hasn't received any answers after the question was asked and there is no duplicate questions. If the OP is not me how to bring that post up?
You could improve it, but these improvements need to be substantial and preserve the spirit of the question. Don't bump to bump
Occasionally "community" bumps up questions with no love - but this is random and automatic.
Posting a bounty's the preferred way, as Serg suggested.
Or you could answer the question ;)
