This whole computer age stuff can sometimes be so confusing. I still remember going through an operator to make a local phone call--and my grandparents had a party line on their phone (their ring was one long and two shorts). So, being able to do all this comunicating in cyberspace seems unreal.
Should libraries use myspace? I really agree with those who stated that if the kids don't want you there, they will just ignore you. But, if the site and info connect with just 1% of those out there, it would be worthwhile. However, I think people are only fooling themselves if they think they can "relive" their teen years by being "one of them". I'm almost (sob!) 60, and for me to post on myspace (disguising myself as a 25 year old library), I think would be a little ridiculous. But, on the other hand, some of my twenty-something co-workers should feel right at home on myspace. I feel as if I'm rambling (but, I must get in my 150 words!).
I think that each library and librarian must decide on the target audience, and then figure out if myspace is the space for them.
