Although I had a brief fling with myspace and have had a facebook account for years, I have never felt even the slightest twinge of desire to jump on the twitter bandwagon. The name stops me, first of all. I will forever associate it with the Disney classic Bambi, in which one character declares another character to be "twitterpated." The word "tweet" is ridiculous to me and while I can control who sees my thoughts on facebook, I cannot control it on twitter...and I don't really have anything that profound to say.
But then, another teacher mentioned that her students had asked her if she would set up a twitter account for homework reminders and so on, and it suddenly clicked. That might actually work.
So I contemplated it over break, and asked my kids about it (and got an overwhelmingly positive response), got a phone that will actually support a twitter app, and decided to just see how it works. The goal is to tweet things like "homework due tomorrow!" and "don't forget to sign up for the blood drive!" you know, lame stuff like that. =)
