Common Tag

[toxin]

Just found Common Tag  is looks interesting. May be useful for SEO as Yahoo uses it the site says Google uses it also. Looks a bit confusing at first( to me) . Not sure how to describe it but looks usable for games.

"Common Tag is an open tagging format developed to make content more connected, discoverable and engaging. Unlike free-text tags, Common Tags are references to unique, well-defined concepts, complete with metadata and their own URLs. With Common Tag, site owners can more easily create topic hubs, cross-promote their content, and enrich their pages with free data, images and widgets."
