I'm starting to understand some of the frustration behind "homework questions" from this thread. I'm being continually asked simple questions that could be answered in 2 seconds with a quick google search. Note that this isn't astronomy-based, but is frustrating nonetheless. Even the links that I do provide go ignored. This diverts me from the actual meat of the debate that has to do with the original topic.

I'm not going to "boycott" all "homework questions", but it's starting to get to a point where I'm not sure if the discussion in question is even worth it.
