When I go to my user profile, I see a list of all the XP I've gotten and given. I wish I could click on other people's profiles and see that too. It would be a great recommendation system -- "see other great posts by this user," plus "see what kind of posts this user likes." If you run into someone with a ton of XP, you can see what made them famous. And maybe they'd even post more just to get a more impressive XP wall.
