I've visited a lot of sites and I think pianostreet.com is the best. I think the reason the forums aren't easily searchable is because they go back years and years and there is a wealth of info hidden away somewhere. I think there should be a weeding out of extraneous and senseless posts: most dramatic piece ever written, favorite concerto, etc. etc etc. Maybe not immediately, but after maybe a 6 months or a year.
