I'm going to keep this short and sweet.
Stack Exchange is meant for people to have a Q&A about questions somebody faces. Not things that you ask because you want to take advantage of a hot topic. Where's my proof? It's in this blog post.
To finish off, let me quote Yannis Rizos's comment on the above blog post:
Hm… I don’t think there’s a problem here, other than trying to make up questions. That’s a recipe for failure, Stack Exchange is supposed to be about “practical, answerable questions based on actual problems that you face” and not questions based on what happens to be hot this week. If your practical and actual problem happens to also be related to a “hot” topic, lucky you, but anything else is a bit fishy.
