If it wasn't for myspace I probably would have missed seeing some of my favourite bands play my city, nor would I have been paid and gained recognition and real life friends for designing a band's profile. I would only know of about half the bands that I like now, as I would never have the opportunity to hear them. I never would have gotten in touch with people I haven't seen in almost 10 years.
This isn't a 'bitch about emo' topic and people that may be referred to as emo are just as sick of your crap as we're forced to listen to it. Can't you just learn to ignore something you don't agree with, I wish I could ignore you ignorant wankers.
