I have found some of these things useful, some which could be useful I can't use due to IT restrictions. Library thing I am experimenting with for RSPB use as well as Blogger.
Delicious has potential use in gathering things together to answer enquiries - what a pity we're not allowed to use the thing on the tool bar.
I am still struggling with the concept of facebook and twitter. Maybe I'll do some more reading about this.
