Naming Policy?

What do you guys think I should do about writing about professors?

I post under my own name and generally make no effort to hide my identity, so I'm always working under the assumption that whoever I write about will be reading this and know who I am (and that I'm writing about them). But I'm still not sure whether to go ahead and use professors' names - it makes things more transparent and possibly more useful to readers, but still feels a little funny. I like the Professor Subject convention.

I ask because I sat next to Professor Criminal Law at dinner and over the course of discussing how we researched schools he mentioned that he scrupulously avoids student blogs because he doesn't want to know what students may be writing about him.
