RDFa Support: How Do Google, Facebook & Twitter Compare? And How Will This Impact Their Position In The Semantic Search Engine Market?
When Google announced Rich Snippets just over one year ago on May 13 2009, they lit a fuse. A year later we saw the explosion when Facebook and Twitter both made moves to support Semantic Web standards. Who could have forecast that?
We are now seeing the great convergence. The new web looks a lot like a triumvirate – Google, Facebook and Twitter. There are other huge companies doing great stuff, but this triumvirate moves the market and defines standards adoption. All three do social and all three do search. So they all both publish and consume content.
On April 21st, we wrote “Facebook just nailed the semantic web“. (Actually, we quoted Alex Iskold’s tweet on that subject and then tried to figure out and explain why he was right).
Since then, we have seen momentum around Twitter Annotations and Google is now talking about how much traction they are getting with Rich Snippets.
In this post we try to dig below the covers to see how this might play out in the emerging new battle for leadership of the semantic search engine market.
