Sergey Brin becomes the first of Google’s three major executives to begin blogging. Spotted via TechCrunch, his blog at too.blogspot.com covers today his personal experience of being at risk for Parkinson’s Disease. In his first post, he explains the name of his blog:

Welcome to my personal blog. While Google is a play on googol, too is a play on the much smaller number – two. It also means "in addition", as this blog reflects my life outside of work.

I’ve asked Google if they can confirm it is indeed Brin’s blog, but it has the feel of being his.

So far, neither Brin, his fellow Google cofounder Larry Page or Google CEO Eric Schmidt blog regularly on business issues, though its something Google would love to see. As Google’s Karen Wickre told me last year, regarding them and Google’s corporate blogs:

The big three? I don’t know. They’re so busy. We’d certainly accommodate if they wanted to. They do, however, appreciate our blogs. I think they appreciate the "direct to you" approach. I’ve worked with them on a few of the posts that are essentially statements. These are a nice way to state our position so that reporters can work from it directly. It also becomes our standing statement on something. That’s been nice for us in a few instances where we’d never put out a press release.

Postscript: You can comment on the blog, by the way, but so far if anyone has tried, they are held in moderation. There’s also a very nice reality check message that comes up if you try to post:

While I would like to receive and post many insightful comments, realistically I am unlikely to be able to read through all of them and may accept very few or none at all. Thank you for your understanding.

Postscript 2: Gary Price of ResourceShelf tells me that Brin and his parents have donated $1.5 million to endow a professor’s chair at the University of Maryland, to help with research into Parkinson’s.
