How I Use It
I run two sites using Edublogs: one for the chapter of Guys Read at our school, and one for my English learners (I'm an ESOL teacher). You can check them out here:
Edublogs is a good choice for a bona-fide classroom blog OR for a less-interactive teacher website.
Being already familiar with the Wordpress interface, setup was easy for me. But if you're new to their content management system, budget some time to learn it. It's well worth it: once you've got the hang of it, you'll be able to build pretty much anything you need.
