For some similar stuff to what you're posting here, I check out popdex and daypop 1 and memepool.com each day. Waiting for Hey Hey 16k 2 to make an appearance, it seems to be doing the rounds, the song is by friend Mark 3 and I know Rob too - isn't the internet like really really small? Gizmodo 4 have run with it and I am sure NTK will this afternoon too. I'm on holiday for a week from today, so if anything happens to this board then, sorry I can't help. Like I could help when I was here...
I had a board here used by the inner circle of popbitch, + friends, to gather content and discuss ideas. I did not contribute to it myself.
