A don't really follow any promotion regularly,mostly just finding shows that look good to me regardless of promotion. The promotion I would say I follow most is 2CW even though I don't buy their DVDs I just go to quite a few of their shows.
I watch what I can when I have time but I'm more apt to read spoilers than actually see matches lately. Whoever makes their product easiest for me to get access to tends to get seen the most.
I try to keep up with EVOLVE, DGUSA and PWG to an extent (and I'm probably the only person here who actually pays any attention to LLUSA). CHIKARA I check out on a semi-regular basis but I'm definitely not going out of my way for any of it. Used to love ROH but, well...not so much now.
