Mathew Ingram has a point - all the conversation about the semantic web turns fairly wonky fairly fast:

Let’s face it -- the biggest problem with the Semantic Web is that it’s as boring as dry toast. It’s all about plumbing and widgets and data standards, all of which have names like FOAF and TOTP and SIOC and whatnot. It’s right off the dork-o-meter. The Lone Gunmen from The X-Files would have a hard time getting interested in this stuff, let alone anyone who isn’t married to their slide rule or their pocket protector. The things that the Semantic Web would make possible are fascinating and in some cases very appealing — it’s just getting there that’s the hard part.

Take RDF (please :) ) - the proponents for that spend entirely too much time telling us what the benefits are, and not nearly enough time coming up with a compelling demonstration. Yes, I know - until you get widespread use, that compelling demo might be harder to do, but you get the idea: with RSS, there was an actual use from day one. With the semantic web, it's mostly verbiage...
