As a program it’s stable, and quite useful when looking for legitimate (non-pirated) downloads. Even when searching for what most of us are searching for, the latest and greatest, games, movies and music in their many categories, I find myself looking to KaZaA and more often than not finding it.
Any of the file sharing networks really are a very powerful tool when in the right hands, and the number of users connected to them is quite staggering despite efforts. Of the file sharing programs, KaZaA Lite Resurrection is definitely the program I use and recommend.
Although it can't compete with full-fledged distribution communities like IRC or Bittorrent due to a great many things everybody, who views a forum like this probably knows about by now. It can be far easier to find a file using KaZaA than searching through channel after channel on IRC or finding the torrent, even after many have been scared off.
Then again, you put yourself on the line when using these networks. As of right now I'd have to say the home user is perfectly safe downloading whatever their heart desires, all we can do is try to support these networks and show the world that this is how the future looks, no matter how much they kick and scream.
