What's the going opinion these days? I did some research and it seemed like Google was giving the strong preference of Microdata. However, some further reading and it sounded like they were pushing it because of their work with Schema.org. However, Schema.org is supposed to be supporting RDFa now (including Google).

I'm having a hard time nailing down which is the "better" spec to follow. It seems like RDFa Lite is more flexible and, possibly, better implemented around the web. I've also seen whisperings that Microdata doesn't work as well with some social networks, specifically Facebook, where RDFa does.

Does anyone have any information on this?
