Quoted from Pdxmonkey:
I think the majority of players in Portland league aren't on Pinside at all.
Quite a few on tilt.forum though.
I agree with this. I go to shows or make craigslist buys and I rarely run into someone who is on pinside, if ever. A few here and there at shows when I ask, but 0 on craigslist buys and a lot of those CL buys people will have 10+ pins in their basement.
