Tags and del.icio.us

Using del.icio.us for research? Its one big advantage is that someone has tagged a website and given it subject headings. By contrast, search engines use automated searching. Search engines don't have real people to evaluate each website and to thoughtfully describe what it is about. The hits are sometimes just literal word matches, not the concepts behind the words. So the hits in del.icio.us could conceivably be more relevant and closer to what you are looking for.
