i think it might limit your sharing, but it seems like the average number of friends is 200 on Myspace.

and some people have upwards of 50,000 friends. i think the people that store the most information, would in turn have the most friends. so you would just need a few friends that store alot of information.

and i do think it would be interesting to see the music and movies my friends have collected. and yes there would be a limited amount of files being shared, but it might be better for both parties involved. One person would have to buy that album, and one person would have to buy or rent that movie, within smaller networks.

and maybe their will be more sharing involved because their would be fewer free loaders. or people sharing just one or two files. because no one would want to be a friend with someone who only shared one or two files.
