I might suggest that you allow the answers and comments to be editable after they’re submitted, like at Quora. It’s far too easy to make typos.

Also, how do you add bold or italics to the text? There should be a rich text editor. I could try using standard HTML tags, but since these comments aren’t editable, I’m afraid of fucking things up. Maybe you could give us a small hint at Jelly? Just saying…
