Why am I doing this?

I have a lot to learn about Web 2.0. I do not use Facebook or Twitter and I struggle a little with the concept of being constantly present on-line and with the interactive side of things. But I would like to learn more about Web 2.o stuff and I realise it may be helpful both professionally and personally. I'm hoping that this programme will help me see what Web 2.0 applications may be useful in my library and at the least that my confidence with Web 2.0 stuff will have improved by the end.
