Answering your question depends on how familiar you are with the Semantic Web.

All kinds of amazing things become possible when websites are able to describe themselves in some meaningful way, or are self-classifying, as with the idea proposed by Sir Tim Berners-Lee, who is a major proponent of the Semantic Web.

Right now, there’s loads of applications that suggest things like nearest hotels, nearest restaurants et cetera, but most of those services rely entirely on people adding those websites to their directories or applications by hand.

If these websites can describe what they offer, there’s no need. Of course, it could open the way for a new kind or spamming, but if we had something that was both elective and democratic — in the sense that you & I could vote and comment on those websites, as we do with Digg and StumbleUpon — the bad would be separated from the good and things like hotels and restaurants would be much easier to find.

Does that make sense?
