WrestlingClassics.com is a very interesting place. The folks there hold their classic wrestling and classic wrestlers (Lou Thesz, Jack Brisco, etc.) in very high esteem. They used to be the butt of jokes on places like A1-Wrestling.com for possibly being a bit too reverent towards some of the stars of yesteryear.
All that being said, WrestlingClassics is a cool place, especially the message board (WCMB). You will not find a more knowledgeable bunch of folks than their message board posters. They are always recalling or digging up YouTube videos of these really interesting moments in wrestling history. I don't post there like I do on A1, but I do lurk and some of the topics and videos I have posted here have been inspired by WCMB. I highly recommend you take a look.
If you care about the history of this industry, I doubt you'll be disappointed with Wrestling Classics.
