Thanks, Diane, for checking in on me. And its funny you mention it because I'd been wondering about the categories. Maybe I'll check out your site again so I can see how an expert does it! I really appreciate your kind words!
I used Blogger for a long time, but switched to Wordpress a year ago and am very pleased with it. The design is very clean (I'm on the "free" version), I've NEVER had an issue with site downtime, or readers having difficulty with commenting. Blogger did have those issues for me on occasion. Wordpress also has a really nice app for posting and editing on the iPad/iPhone, which is great when you have to post in a hurry and realize when you are out and about that there is an error that needs fixing. :)

Best of luck - let me know if you need any assistance!
