I agree with Adam and Neshura. Voting should be primarily an attempt to grant XP to the author of a well-written and/or useful post (or, conversely, to inflict penance on a wayward monk).

I like the incentive to participate in this great site, and you should continue to give XP to those who vote, but perhaps on a decreasing scale (The first vote has 25% chance of +1, but the chance for XP declines for each vote thereafter.)

P.S. The XP nodelet shows (as I am posting this) that I have graduated to level 2. Now I'll see what voting is really like... :-)
