What is the point of having separated Open Threads and Stupid Questions threads, instead of allowing "stupid questions" in OTs and making OTs more frequent?
You are allowed to ask in the open thread. I don't think having it more often would help. The SQ thread is for things that you are embarrassed or afraid to ask elsewhere. Apparently some people have questions that they didn't bring up before the first stupid questions thread.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
