Jack Vinson is teaching a class at Northwestern on knowledge management. One of the assignments is flogging (forced blogging).
In his post on the Initial impression of Blogs, one of the key issues his students raise is the privacy factor. Most of students seem to operating under pseudonyms. One even added security (blah blah blog).
A few point out the Wall Street Journal article: How Blogging Can Help You Get a Job. They generally seem to be contemplating what to do with their blog. I assume this stems from the forced nature of the blog.
I found it interesting to compare this experience with Enterprise 2.0 blog issues raised by Andrew McAfee's class.
