i'm not really sure, i've only been using it for awhile.. its really about the friend status from what i see though - who is in the Top 8 on a friends page and stuff. i don't like it from a personal stance as much as LJ -- too cumbersome to use first off sometimes -- but its more about networking, finding people and making a connection.. LJ is harder to do that with but its getting better with the school additions - which is what myspace is useful for.

i've not added several people and not had any backlash, but you never know.
