José Saramago, famous writer and stealer of my ideas¹ has a blog in Portuguese and Spanish. If you read either of these languages, it is worth checking out; Saramago is very much into writing essays in the tradition of the "autonomous intellectual," commenting on the absurdities of society from a distance. This style has its drawbacks, and certainly doesn't pass muster in academia, but it is very fun to read. I would prefer it if he would use hyperlinks, but I'm sure he has his reasons for not doing so. He's the first major author that I know of who has started a blog (of course, I'll probably find a million more if I just google search).

¹I am, of course, kidding. Please don't accuse me of defamation.

Update: I think I was a little ungenerous in my initial description of Saramago's blog. The description of his blog as "commenting on the absurdities of society from a distance" certainly applied to the post I was reading at the time, but many of his other posts show a more engaged, thoughtful style.
