Bill Gates launched his personal blog called The Gates Notes this past week. He has a category for Education and already posted a piece on lifelong learning and some courses he has downloaded from The Teaching Company and a post on educational reform. He says that he will be posting about open courseware soon too.
The navigation is a bit too elaborate and I didn't find an RSS feed to subscribe, but it nice looking. It looks like he has good tech support.
Has Bill turned into an edublogger? Not quite, but it's certainly on his agenda. I like that he has a category for what HE is learning about these days (economics is on that list).
From what I have read about the blog, it is actually Bill doing the blogging. I hope so, and I hope he keeps at it and doesn't pass the writing over to someone else.
