LimeWire is all about File Sharing. Not sharing any files is like attending a pot luck and bringing only your fork.

Trouble comes when sharing (a lot of) copyrighted stuff. There are a great many movies, songs, etc. that are in the public domain and can be shared without worry.

Browse a few hosts - you'll see good and bad examples of file sharing, i.e., some people share their entire hard drive, as if we would want to download their 'letter to mom' or their last year's tax return. That's not only stupid, it's like bringing only horseradish to the pot luck.
