Minimum is maximum

I'm happy having just gmail as email, blogger as blog, and MSN as chat. Since I am a bit over, I have a UOL fotolog, yahoo messenger (which I barely use), Skype, UOL Phone, Gtalk, Orkut. Those I still can manage. But what the heck should I do with Hi5, Tagg, Multiply, My Space, Linkd In and so many other stuff I receive invitation to join?! Honestly, can somebody be everywhere all the time properly???? I like to talk and tell stories, but I barely manage three (photo)blogs. I wonder how much free time one has to have to be all over the net.
