Ok so there's not 400 on the list, but there are at least three billionaires who blog:
- Pierre Omidyar, $10.4 billion
- George Soros, $7.2 billion
- Mark Cuban, $1.3 billion
A little bit surprising that Bill Gates, Paul Allen, Steve Jobs, Sergey Brin, Larry Page, David Filo, Jerry Yang, and Oprah aren't on the list. Come on gang, TypePad is only $4.95/mo.
