I'm working on modifying a mod on microblogging for a course I teach through U.B. Last semester was the first time I had included microblogging in the course. I found that the students used microblogging like a form of short emails. I hadn't shown them how Twitter can be used not only as a social networking site but also as an educational networking site. Part of the problem may have been that I had them watch Lee LeFever's video which explains microblogging in social terms.
So this semester I'm going to have them read articles on educational microblogging, search for an educational term such as connectivism, check out the sites of others who posted on that subject and follow some of these people for a week.
In planning this mod, I reread all the sites that I tagged as Twitter in my delicious account and retagged them as TwitterTutorials, TwitterTeachers and/or TwitterArticles. This sorting helped a lot.
I also listened again to this great viral video by UK musician, Ben Harper. Check it out! :-)
