I only like to use places where users can comment on the torrent. Otherwise 80% of the time you'll be downloading crap or viruses.
So I'm using this right now:
btjunkie - the largest bittorrent search engine
Does Rapidshare have user comments?
torrents are weak. rapidshare + forums like warez-bb.org (been up and down lately), linktalk, tehparadox is the way to go. set up fleshget with your rapidshare account and just highlight the links, I download movies in about 7 mins. And yes you can see comments, as the links are posted in threads.
what.cd (music), tehconnection (movies), demonoid (whatever else), TPB & isohunt (sometimes)
