In my case my XP just denotes that I've been around here forever. In comparison to the esteemed mindtrust around here I'm still an acolyte at best. The daily login and XP for voting is a small part of why I show up every (work) day, and I do learn a nugget here and there by doing so. I like the fact that my daily participation in the board is somewhat reflected, even if my contributions to the content have been minimal over the years.
