Kingsley Idehen, CEO of OpenLink Software (and InfoWorld Innovator award winner), corrected me.  Apparently he does have a blog!  I'm subscribing and so should you, this guy has a great understanding of database technologies, unified data access, and the importance of platform portability. 

Even better, his product Virtuoso has some interesting blogging support that he'll be demonstrating soon.  I'll post when I have more details.
