Del.icio.us, Technorati, Tagging,Library 2.0

I used Del.icio.us PLCMCL2 and went to What the Director is reading. I found this might be helpful for reader's advisory but am not sure of how to use it myself. Technorati was also looked at. I looked at several of the top blogs and favoirte searches. It definitely seemed more like a social thing then anything of great value to me. Library 2.0- After reading articles on icebergs , I think it would be interesting to meet with librarians in the system and discuss the changes in the future or as I get more comfortable with the blogging and chatting to discuss it on line. Being in a branch that likes printed material, I'm wondering how this online will go over. I do agree that if you have to train than the system is too difficult to use.
