I just heard this term used to describe an academic blog that serves as a central hub for the assigned blogs of students in a course (or at least I think that’s how it was being used). [heard on Gardner Campbell’s audio recap of his faculty seminar on new media being re-posted/hosted at nmc by Alan Levine.]
I’m digging it, and am wondering if this practice–of asking each student to write their own blog and collecting them in some way on the web–is so prevalent that it has garnered it’s own nickname, or if this is a term that is being carried over in some way from somewhere else around the web.
Regardless, I’m about to head up a workshop in my new media seminar that will culminate in my own “motherblog,” and am looking forward to using the term egregiously. 🙂
