I've noticed a good amount of our downvoted, closed and migrated questions tend to be of the "Please suggest an icon/color/ect" variety (such as this recent example), where people don't have an explicit question, but rather want some ideas on what to do.
They're not all bad questions, and some of them can be rewritten to be on topic of a specific but not personal UX issue, but I see them fairly often and almost always with a downvote or [closed] tag. Should we include a blurb about "Suggest" questions in the FAQ? I noticed there's nothing explicit about them in the "What Makes a Good Question" section.
I think it's inevitable that a UX site would get a lot of these so I think formally addressing them would be ideal; a lot of people designing products tend to be thinking "How should I do this" when our answers are really "Why should you do this," and the question should be formed in that frame of mind.
