As the number of people in the network grows, the connectivity increases, and if people can link to each other's content, the value grows at an enormous rate. The Web, if it were simply a collection of pages of content, would not have the value it has today. Without linking, the Web would be a blob of disconnected pages.
As information professionals and librarians, we shouldn't miss out on the obvious links between Web 2.0 and the Semantic Web. Social networking is critical to the success of Web 2.0; but by combining the social networks of Web 2.0 with the semantic networks of the Semantic Web, a tremendous value is possible. Here's a scenario from Tom Gruber which I find very compelling:
Genius.
Real Travel "seeds" a Web 2.0 travel site with the terms from a gazetteer ontology. This allows the coupling of place names and locations, linked together in an ontology structure, with the dynamic content and tagging of a Web 2.0 travel site. The primary user experience is of a site where travel logs (essentially blogs about trips), photos, travel tools and other travel-related materials are all linked together. Behind this, however, is the simple ontology that knows that Warsaw is a city in Poland, that Poland is a country in Europe, etc. Thus a photo taken in Warsaw is known to be a photo from Poland in a search, browsing can traverse links in the geolocation ontology, and other "fortuitous" links can be found. The social construct of the travel site, and communities of travelers with like interests, can be exploited by Web 2.0 technology, but it is given extra value by the simple semantics encoded in the travel ontology.

Nice. Golbeck and Hendler make the connection between social tagging in web 2.0, non-hierarchical semantic relationships and poor findability.
I don't get why Plutchak thinks the semantic web and web 3.0 are unrelated concepts. I say in the BMJ piece that they are seen as both controversial yet complementary.
Your post suggests that there are some possible solutions to poor findability by using both web 2.0 and and the semantic web. I agreed with you, then I changed my mind in the BMJ piece.
However, I still see the point though I wonder how it would work in reality.

Dean,
This is certainly worthy of an intellectual debate. I can see why Plutchak argues for the rigid dichotomy between Web 3.0 and Semantic Web. While Semantic Web technologies already exist (albeit in its infancy), "Web 3.0" doesn't really exist yet. My perspective meets his half-way. I believe Web 3.0 will rely on SW technologies -- but it's different in that Web 3.0 will extend beyond the traditional computer and web browser. It's going to be about integration with things such as the Slingbox and the iPhone, which the Semantic Web clearly is not about.
As for Web 2.0, I see it as stage that leads to the Semantic Web, and ultimately Web 3.0 (whenever that will happen...). SW will depend on ontologies, which will need some sort of social folksonomy, in order to work. That's where I see the most important link to be.
