i think facebook is more community orientated than myspace, but myspace lets you be alot more creative in terms of profiles, which i like because it gives me something to waste my time on. but i really like the facebook commenting/wall-writing system-- so speedy!! they both seem to suck off each other though, with the whole photo-tagging business. that is so facebook.
i would use facebook ALOT more if more of my companions used it, but they don't... and i really like myspace bulletins. so much entertainment....
FB applications are crap.
