As I already have a Facebook page I didn't have to set this up. I only set up the Facebook page because some friends who I met on my last holiday had put their photos on Facebook and I wanted to see them. I actually quite like Facebook and it has the added bonus of knowing what my sons are up to! They added me as a friend ('cos I didn't have many and they felt sorry for me!) and now I know what they have been up to in the last few hours, what they are planning on the weekend and explore their photos, know what their relationship status is etc. Mind you sometimes I don't want to know or wich I didn't know!
Before reading about social networking sites I didn't actually think about applying them to an organisation or business so see that potential now.
I still can't get excited about Twitter. Some people have too much time, however am prepared to change my mind!
