If you’ve ever checked new on askreddit, there were quite some questions like that on there too (and people usually answered them because… well why not I guess, everyone’s just killing time on there anyway).

I think as long as there aren’t many posts anyway, it doesn’t really matter. Once there are, it’s unlikely the not open ended questions would get much traction. Maybe /r/outoftheloop or /r/nostupidquestions style posts would also get upvoted, at which point it would probably make sense to seperate the concepts. For now that seems a bit needless imo.
