Kazaa is dead. They're being sued, and you can't really find anything good on there in the first place.
BitTorrent is the current big thing, but the MPAA is filing lawsuits against trackers, and the biggest one, Suprnova, just called it quits.
Kazaa Lite Revolution is far from dead and still returns more hits for any given search than any other P2P program I've found.Kazaa OTH is chock full of spyware,pop-ups and requires a subscription.If people are willing to pay for the security of downloading without being sued I say more power to them.
