I just spent the last couple hours doing a touch of redesigning and I think it worked.
So the main page will now show the last 10 entries across all the blogs in order. Instead of just the last entry from each one. There's links over on the right that go to the main page for each individual blog, and I think I have the comments fixed. I know they're fixed for sure on the book blog and the photoblog. I'm going to go check the other three now, but I know what was wrong with them so it's a quick fix and by the time anyone reads this it'll probably be done.
