You know, I find it interesting who decry people who enjoy social networking as having some sort of narcissism about them, that the people who involve themselves in it deem themselves so important that others *must* know the minutia of their lives.
That didn't start with Twitter. Or Facebook. Or MySpace. It started back in the day when people wrote raw html code in order to put a personal webpage up. Which morphed into blogs and wikis. In other words, it's the beauty of the Internet. It allows people to express themselves in ways they didn't have before and share information.
I like Twitter. It's not because I enjoy telling a bunch of people when I sit down to eat, or when I'm going to sleep, or my drive into work. I try to be interesting and share things I think might be interesting to others. Likewise, the people I follow I find interesting. I've also found that searching for topics in Twitter is one way to get an honest assessment of what's going on and how people think.
So hey, it's all well in good if you wish not to participate. It's your life. There are plenty of things I choose not to participate in.
But I've never derided those activities as "retarded". I'd like to be given the same courtesy.
