I've been using the Regulus theme for some time, but I have noticed that it does not include the basic meta-tagging required for Google's rich snippets.
I'm technically able to do this sort of thing in the templates, but can I edit my theme on wordpress.com? It does not appear so, and the Custom Design upgrade doesn't really say.
So: is there a selection of themes that DO include Google markup that I might want to try out instead of Regulus?
The blog I need help with is matter2energy.wordpress.com.
