Is it really that important? Most users don't post things that are long enough to justify the extra coding and server space. Not to mention the fact that many of those who make long posts take the time to type them in word processors anyway. No, I say leave the auto-saving drafts to the blogs. I think there's a reason why you really only see them there, but I can't really say why, so please pretend like I just said something insightful that makes you realize that they only belong in blogs. Also, to clarify, the feature would really be helpful, but its labor and used resources probably wouldn't be justified. Also, that first paragraph really wasn't necessary. I bet I could have used the sentence above and made my point just fine. Oh well.
