Back on Twitter

So after my Twitter post from a few weeks back, I signed back up and found that a LOT more of my friends have joined in the last four months, so I'm going to give to a go yet again. I'm on there as LeslieCaro right now (though I may change that--apparently choice of Twitter name is a big deal). Follow me and I'll follow you! I also would be grateful for anyone who is a Twitter pro and can offer me a cultural introduction to it...
