It does come up as a status update.
But if it's a real question, it can be moved by an admin/advisor to the questions page, and then, a random category (using keywords) would be assigned.

I think it comes up as a status update sort of thing. Kind of like a comment....? But it only shows up on their wall...I don't do it often, I'll have to make sure. :)
This was a question I asked in someone's box :) Apparently it comes on to the main page, but I cant pick a category
