It's easy in hind sight to think your question was not worthy of being asked but you wouldn't have had it if you had known the answer at the time. We all know different things; look at any trivia game show on TV. If it's important to you to know, ask it; who cares what other people think, they're doing their own thing, needing their own answers. You probably have the answer to some questions they'd like to ask but are afraid of just because they think they'll look stupid. You're brave, you asked. Keep asking!
