I've noticed that many of the Lifehacks questions I've been active on stay open for many months, and never get an accepted answer.
This is not true for most of the other SE sites I'm active on (AskUbuntu, Role-Playing Games, Science Fiction & Fantasy, for instance). My own suspicion is that the nature of Lifehacks is that there may be no one best answer for many questions lookign for a lifehack -- and if that's the case, it doesn't bode well for this SE.
Am I wrong? If so, is there a workable way to encourage answer acceptance?
