Hey Steve, I was late night wittying and had a good idea! So maybe to cut down on vent quotes or negative quotes. Maybe you could have a page on everyone's profile to some kind of witty journal. You could add a feature for each wittian to be able to make journal posts and they won't show up as quotes. And people could see them if they wanted to because you could have it be part of their profile! I hope this makes sense it's sort of late...
You're quite awesome yourself :3
