I've been on twitter since April, I think.
I teach in a small urban high school. Of the 6 math teachers at the school, only I am really online with regard to anything at all relating to math.
The MTBoS is the math department I could never have imagined belonging to. I find the relationships I have formed in twitter to be just as fulfilling and enriching as many of my off-line friendships.
WHO would i like to meet: TheJLV. If I met you in real life I'd hug you and invite you to meet my students. I hoped you see the promise in the future of this country and its citizens. I recognize that we're not there yet, but the next generation is very accepting and non-prejudicial in a way no previous generation ever was. He understands that equality in education, mathematics especially is key. If you've not followed him, you should be.
WHY twitter ROCKS: If you don't know about twitter chats, please let me inform you. This is the most valuable thing about twitter to me. On Mondays I participate in #alg2chat a forum in which topics, standards or whatever you want relating to alg2 , by alg2 teachers is discussed. On Thursdays I participate in #statschat and #precalcchat, at the same time and haven't left a chat without something valuable each time I've participated. The #msmathchat on Monday nights has trended on twitter overall a number of times recently. Props to you guys!!
Then again there is my MTBoS crush... Fawn Nguyen...but that's another post...
