I'm a big fan of MIT's Technology Review magazine, and I was thrilled to see in this month's issue that they have a blog. Turns out they've been writing it since October, so either I've missed previous announcements or they've been shy about it up till now. Anyway, it's a group blog with permalinks, archives, and XML feed, and comments, and it looks pretty good to me. I'll be adding it to my sidebar. Check it out.
