Sometimes a question pops into my mind a mere 5 minutes before I have to run an errand. In that situation, I can either: (a) write the question down on paper and ask it later, or (b) ask the question very quickly, but perhaps with errors that later need editing. I generally choose (a), which isn't altogether that inconvenient.
But is there any way that we could have a "Save Question as Draft" option? I think many users would find it very convenient.
Aside from the rushed scenario I mentioned above, there are also many times when my thoughts aren't fully clear, or my phrasing could be ironed out. It would be nice to be able to begin writing a question without feeling as if it's a final draft. (I know that there are "edit" options, but one never wants to edit too much...)
And given all the recent discussion about the quality of questions on this site, perhaps such a mechanism would encourage users to wait a little longer before posting.
