Hakia and semantic search

For those of you who follow Joyce Valenza, you may have seen her post about the semantic web.  I enjoy her blog very much, but I sometimes need smaller bites.  Try Hakia, I did.  The results are very interesting.  First, they are sorted by type, but if you look closely, you will notice that you get a much different class of results and they are also snipped and the search terms you used are highlighted, so you can make a judgement about the context of your search term and whether the web site or blog is one you want to click on or not.
