Perhaps you all know Sergey Brin, the Google Co-founder. I just came to know that he's started his own blog at http://too.blogspot.com/.
"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." - Sergey Brin
The above is what the first post read. The post was dated 18th September and by that, I could just comment, despite of all the bloggers' stuffs and services Google is providing, he is a REAL LATE BLOGGER!!! I don't think he owns any other blogs as per Matt Cutts's remark.
Keeping in track of his blog, Sergey has the Google Analytics installed on his blog; perhaps knowing that a lot of people will be giving him free suggestions on Search Engine optimization or on DIY - tweaking blog template.. which would sound rather funny if for the Google creator!!
In one of the short 2 or 3 posts at current, Sergey mentioned about the likely development of Parkinson’s Disease on him and which might affect him when he’s older.
