Hey Big,
I don't think it is slow, I just think there's not much going on due to the decreased number of products being released. Yeah, summer is slow, but no releases equals no trading, especially for set and player collectors. I actually started working on some of my vintage sets this week and I've been getting all sorts of replies and trades done.
Do you have any projects that you've had on the back burner for a while? Now might be the time to put some effort into them.
Just my .02.
Good luck with your collection!
