Yeah, I think MySpace is a design nightmare. I mean, you have to give non-designers at least some guidelines, rules, a fence to operate within, or else you get , well, you get what you get not on MySpace: bling-ed out pages that could quite possible be dangerous to the epileptic.
Still, there’s no way you can discount the value and importance of MySpace in the music realm, because almost every single band, famous or trying, has a page there. It’s the default online property for musicians, still.
And that’s exactly what I use it for. I have 400 something ‘friends’ and every single one of them is a musician of some sort. Doesn’t matter if I dig the music or not, when I happen upon a band online, I immediately follow their MySpace link and add them as a friend. It’s become a music repository, for me.
And when regular people ‘friend’ me I decline. Except my mother, you really can’t reject your mother, so she’s the only non-musical contact I have.
What I’ve done is make MySpace work for me, and this flexibility exists on most social networks. They offer you a model that can be tweaked to function in ways that are valuable to you.
You should cruise my list, it’s an awesome little (growing) collection of hip-hop, electronic and disco, and yeah, some sucks, but most is really cool. If you’re a musician, friend me, I’ll accept.

What a COOL idea!
