It used to be that when using Napster I had to post my connection speed as lower than it was, because too many people were uploading at once, causing transfer errors. Then in the last month or so, I was able to truthfully list my connection speed. Now, the filters are knocking off about 94% of my files. I go on to Napster for a few hours and nothing happens. Whereas I used to go on to Napster to support it, lately I've come to the conclusion that the hamfisted sloppy filtering is Napster's fault, rather than Patel's. They've had plenty of time to develop a better method. I'm starting to develop a cynical attitude towards Napster, not unlike that of 9504, but I still haven't deleted it because I like to see what they're up to from day to day.
I've been waiting to see what other file sharing programs will become a good replacement, and so far I've seen Morpheus mentioned the most, but I haven't dumped Napster yet. Check this link out, which reviews some Napster clones:
