i post on KLOV and on here (really just started posting here...have been a lurker for a while).
KLOV has a lot less traffic on the pinball side of things.....that's actually a good thing sometimes. i have really enjoyed the threads here on pinside, but there are a TON of more members. that sometimes makes navigating threads a chore........there can be 100 new posts in a few short hours here and that sometimes makes it tough.
i enjoy both though. pretty good collection of posters from what i've seen........and i mean on both sites.
RGP is fine, but to be perfectly honest, the format turns me off so much that i can't bring myself to post there. good site to go to for info, but they really need to do something with their format.
just my two rusty nickels.
