If you’re tired of Napster’s pathetic UI and frequent crashes, try the Scour Exchange Client. The UI rocks, and as a bonus, you are no longer limited to sharing music, you can also share photos (umm, think of the possibilities… ) and video. And it’s far more user-friendly than Gnotella. Of course, it will be some time before Scour builds up quite the same community as Napster has, but it’s starting to look good.
