I tried Twitter, but I didn't use it much. I read other people's stuff, but being the high-tech hermit that I am, I don't much need to keep in constant contact with anybody, so the system doesn't have much utility for me.
Without a cell phone, I don't really feel the need to constantly send out text messages to folks. I just don't have that much to say that fits in 140 letters.
Obviously, this century is designed for folks born after I was.
