For instance, a search for "Dare > > Obasanjo" could be looking for me in many contexts, it could be Yeah, I think it goes even beyond this. Like nobody bothered to figure out *why* the author would spend all of that time categorizing everything in various taxonomies. And even more importantly, how someone would add metadata about some web page that they don't own -- because to be truly in the spirit of the web, anyone should be able to publish metadata that anyone else can access. And then, how about all of the purveyors of badness who stuff their pages with deceptive meta tags to fool the search engines? I think meta tags in web pages were not a very practical start for a semantic web. This is where google has a head start on most everyone. The interesting metadata is *not* the metadata that the resource author publishes about his own resource; it is the metadata that is published independently of the resource. Number of inbound links is one bit of metadata about a page. Google randomly assigns search results to be "click-through" so that google can sample which pages are most likely to be clicked by users -- this too is independent metadata about a page. Now people running the google toolbar can have their machine automatically upload statistics about which pages were visited. This is metadata about those pages (7 users found this URL interesting enough that they browsed the page). In the first case, google is mining for metadata, and in the second two, google is using observation to capture metadata. But it would not be a terribly large step at this point to allowing a more direct user participation in the metadata publishing.
