Tom Kyte Has Started A Blog
Tom Kyte, who'll you'll probably know through the AskTom site and the "Effective Oracle by Design" book, has started a blog.
Tom's site is another one of those hosted on blogger.com that you might not be aware of as the site feed isn't syndicated on orablogs.com - I think this is because blogger.com uses ATOM and orablogs currently only aggregates RSS feeds. I'll have to drop Brian Duff a line and see if he can add ATOM support. Anyway, here's some blogger.com-based Oracle RDBMS sites that you might want to bookmark.
