Gridcoin because I like the fact that I'm contributing to something other than trying to making money.

gridcoin could really excell!
Can you have twice the fun, i.e. mine Gridcoins with BOINC running and get both extra GRCs and Ripples via the community grid project?
if you run WCG in BOINC, you earn ripples...i don't know how you can get extra GRCs with wcg...
