Blog "platform" musings

I love blogs and blogging, and have been trying (not entirely unsuccessfully) to promote them at my college. I have a class of students set up in LJ - somewhat by default because it was the easiest platform to use and get them into quickly (you can see them by going to debbie_g and checking out the friends page). I have a Vox account and a Blogger account, neither of which I use, and have been asking my college to install Moveable Type so that we can have a simple, clean interface for students to use. If that happens, I will move my debbie_g account there.

( But all this makes me think about why we choose one platform over another. )
