You know, I've had this idea too, and it plays with Leonids suggestion.

Customizing your posting space whenever you post. See, people like it when they stand out from the rest of the crowd. May it be something completely different with your name or you have a fancy little graphic thing embedded into your post (that's very subtle).

I think finding a way to add optional customization with the customization we already have might help this problem.
