i use FB for friends and family overseas (NZ/Chile/States and Asia) other than that not much. I LOVE twitter - on there everyday - use it as a tool for information (more up to date than the actual news), follow sports, a lot of mum/child blogs and i've made a lot of friends too. I've won a lot off twitter too. It has been invaluable for advice on a toddler aswell as I don't have any family around me and have a lot of time just on my own with my daughter. i#ve been using it for about 3 years now but using it pretty much a lot over the last year.
