My previous post was about the search web site Snap and here is another nice and interesting way to search the net: Quintura - see & find.

Quintura uses a nice concept in which you start with a search term and the get a cloud in which you can include or exclude matchings to refine your search, all is done visually so you can see how your cloud evolves when you’re refining your search.

The image shows a search for SharePoint and then server was highlighted.
