I maintain two blogs. The blog on Blogger is more focused on the web design and development business, the Tumblr blog is a more personal thing.
Just to keep things interesting, they both are named the same thing: The Quiet One.
The professional blog is at http://razrgrl.blogspot.com. The book I'm Doing What Now?! The Office Worker's Guide to Managing a Website When It Just Gets Dumped On You is being released in full on this blog -- if you have the patience for reading in reverse chronological order.
The personal blog at http://razrgrl.tumblr.com. This is largely about my kid, my dog, Lord Fuzzbutt, and my adventures in the wilds of suburban Maryland.
