I couldn't get any site to *really* work except the emotion one. The news one was just a bunch of floaty stars and the Wiki one only showed links from searched article's main page. I guess I thought it was going to show me all the places that subject appeared in all the articles of the wiki, but it seemed no better than reading the wiki entry itself. 

Some good examples of this kind of mathematical/ visual mapping that you might enjoy can be found on Librarything.com where it shows all a user's books weighted by author or subject etc. or those of whole communities and then the "Zeitgeist". This, for example is the "author cloud" of the top 75 owned books by members of the librarything community: Zeitgeist Here's tags. etc. 

Also, if *you*? are building the wiki one you might want to make it un-case-sensitive. The emotion one worked fine (although a little slow despite the fact that I have a cable connection) ciao Saudade7
