Academics and blogging

From Paleojudaica an enjoyable couple of links to Why are there so many of the leading bloggers academics? and How do you get an academic to blog? -- from The Volokh Conspiracy, which I hadn't seen before. The latter certainly applies to me. I enjoyed reading Paleojudaica.com and the idea had never even formed in my head to have a go myself until a remark from Jim Davila to the effect that it would be good to see more blogs in related areas. As for why blogging is popular among academics, I'd guess that it's as much as anything to do with the very simple fact that we are used to writing a lot; it's one of our most basic ways of communicating.
