A timely poll, I just tried FaceBook and Twitter for the first time this last week.
Yup it was all those folks from high school that I really don't know now and mostly didn't know then. 40th reunion of all things.
Gave them both a full week of my time. They had nothing for me, nada, no attraction at all. Folks that wanted to be my friends were not at all interesting (which may say something about me). Those things I was interested in tracking via twitters were overflowing with idle chat and with little solid content.
Eh.
