A search with Tafiti (Image from: WikiHow)

Tafiti is a Silverlight (“Microsoft’s Flash”) based research tool. It uses the Live search engine to power its results. On the right side there is a place where you can save pages for later reference, and you can stack them to for similar topics, you can also label the groups too, so you remember which stack is which. You can also save these to a Live Space or email it to others.
You can select what you want to search for from the little circle thing on the bottom left side. A nice feature is that you can easily “filter” the results (adding a second search term) by using the box at the top right corner of the results page.
A cool thing you can do is that you can change the results into a 3d “tree view” giving you a web like view of the results that you can rotate.
The thing with Tafiti is that although it is cool, it isn’t that useful as it uses the Live engine which isn’t that good. If Microsoft comes up with an app that will allow you to use any engine and integrate services and sites like Wikipedia and Digg, it could be a great tool.
