Ideas 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
