Come to think of it, I have been known to send pictures to my daughter and vice versa, and include text on that. Generally though, if I send a text message I'm replying to one someone sent me.

I did consider twitter briefly, but frankly a) I don't think anybody NEEDS to know that I just crossed the street or ate a hot dog and b) I do NOT want to pay for near constant text messages. I do have an account, but I use it on the computer to see what Mars probes and things are up to.
