Ease of use
 

It is my humble opinion that gnutella (and it's clones) will have a very hard time following in Napster's footsteps. I know gnutella wasn't borrowed from napster, but gnutella is just too hard for the average napster user to learn in a reasonable amount of time. I know that everytime i've wanted to download something, I always get these "push" things in the status box. Now that I am (somewhat) experienced with gnutella, wouldn't it be great if it had true queue ability?
