I am really starting to use Sphere.com quite a bit. As a blog search engine it is quite adequate. But the beauty of Sphere is when I added the “Sphereit!” bookmarklet to my Safari Browser (Firefox is also supported). Whenever I wish to know what is being said about any particular website I am visiting, I simply click on the “Sphere It!” button , and I receive a list of blog postings on the web which may be related to the subject matter of the site I was visiting.

Too cool.
