Yeah, everything's going to be text editable. The twitter #hashtag model is what we'll probably follow. So if you type, say, "!" it might pull up a date picker and then when you choose the date it'll insert it in the text like !2010-10-24 (and record the metadata invisibly for sorting/filtering and whatnot).
