Even if there are some pieces of evidence that it is the real Sergey Brin, I still doubt of it.
His Blogger account has been created this month.

Ok, the small domain it's a good reason to believe it could be. But... that template? No blogger ads? No photos? Uhm ... I don't believe it too much by the moment...

Hmmmm, I wonder if Sergey is friends with the FAKE Steve Jobs.. ;)

I first spotted this on TechCrunch today:

Sergey Brin starts blog, tells of Parkinson's risk

> Ok, the small domain it's a good reason to believe it could be.

Hmm. I find it hard to believe that nobody else has claimed that blog address before. Many 2 and 3 characters combinations have already gone. (If I could be bothered, I'd run a script to find out which exactly are still free... anyone fancy doing that?)

Try to post a comment. He (indeed, if it is him) has got comment moderation on (unsurprisingly):

<< 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. >>

I'd suspect it is real:

Matt Cutts has confirmed it's real:

<< I’ve checked with folks at Google and they confirmed that http://too.blogspot.com/ is Sergey Brin’s blog. >>

Perhaps it's a fake Matt Cutts too! :-P

My eyes hurt reading that blog :(

Well, if Matt Cutts says it's true, I'll believe him!
(subscribing to the RSS)

Just FYI, Matt updated his post pointing out analytics. Analytics show "UA-5667167-1" meaning his account number is "5667167" and "1" meaning one profile associated.

A few sources say it's Sergey Brin, including the Official Google Blog on the right side of the page (section "Blogs By Googlers"):
