Inane drivel. I have a deep, burning, vitriolic hatred of almost all types of social networking - Facebook, MySpace, Twitter, deviantArt, et cetera. I do see the point, but I don't use them and I never will. I don't need to alert people to any random thought that pops into my head, I don't want every detail of my life be accessible with a simple search, I don't need entirely disparate people (i.e. my online friends and my RL ones, and my RL family) meeting. IMO, using social networking sites like this for other than official/commercial purposes (i.e. band pages, political twitter accounts, etc.) assumes a level of self-importance and self-centredness that I just don't have. Like I said, I don't want the whole world to be aware of everything that goes on in my life. Why would anyone be interested?
*ahem* I don't use Twitter.
