I used to keep track of my DVD collection via a customized blog, but I let that fall by the wayside, but now I'm keeping track of my Blu-rays, at least, on Blu-ray.com.

They also let you post pictures of your setup, so here's mine:

My Home Theater Gallery

It's outdated, of course, and will be even more outdated when I receive my EP800s and additional QS8s, and much more when I'm finally able to move it all into the basement. I don't know if I'll post new picture until that final move, as the living room is a little hideous right now in a state of transition. The window behind the couch was taken out, as behind that is now the independent stairwell to the basement. Right now it's some crappy patchwork, but eventually the wall will be done with some measure of soundproofing.

If anyone else is registered there and would like to share their links, that would be great.
