I want to say I think this is one of the best threads I've been on. Some of the other sites that interest me, I don't (or rarely) post on because they become very contentious and always seem to be arguments instead of discussions. Many subjects break down to insults and fights! While you can expect that from time to time anywhere, on this site I never feel like there's a problem with posts.
After all... The Beatles are about fun! Their inovative sounds and humor are unmatched (IMHO) and never will be.
All the forums I visit have ebbs and flows so I'm sure this will pass when someone hears or see's something interesting.
I for one am very glad to be hear (get it!?) with some like minded musical people.
