New Layout - Accessibility check, please?

Hey everyone, no new content today.  Just wanted to announce the redesign - I got tired of wrangling with a template designed for the old blogger interface and being unable to edit it easily; besides, it was really time for something new - and ask if anyone has any accessibility issues that I need to address.  I'm no expert on web accessibility, but I do want this space to be accessible for all, so please let me know if there's anything that needs to be changed!
