Teachers Using Microblogging

I looked at this article:

I think that I'd use Microblogging as a get-to-know you tool at the beginning of the year. I'd have students create profiles and post things about themselves: interests, likes, dislikes etc. Then I'd have the students go on during class and check out each others' sites. I'd also try and create some games or activities that would ensure that the students were reading each others' blogs, like 3 lies, 1 truth, and the students have to guess which one is the truth about their classmate. I do worry about things like cyber-bullying or the blog being infiltrated by people that aren't part of the class, but I'm sure as I became more familiar with the site I'd be able to figure that out.
