I think that Google wants everyone to optimize FREEBASE and start using ACRE. Go watch the youtube video from Metaweb (now Google Freebase) - if you are not familair with Freebase, you should be. What does everyone think about the new "entity search" and "meta information" as it applies to SEO? I think that at least having your site registered in FREEBASE is like on the basic top ten SEO things you can do for yourself right now, but I don't see people screaming about this... Acre is the API for freebase - and I highly suspect is prized by Google. Google's recent crackdowns make sense if you put them into the context of what they are trying to accomplish with freebase and entity based search... Opinions anyone?
