Wyzo

From here you can search services like Metacafe, Photobucket, Technorati, Bloglines, Amazon, Vuze, and Mininova, in addition to those already mentioned. The information found at the bottom right part of the browser is also very interesting. It includes the PageRank and Alexa ranking of the website you're currently visiting. You can also look up the number of pages indexed in each search engine or do a Whois on each domain name. In the not-so-distant future Wyzo will integrate a BitTorrent client to allow for P2P downloads from within the browser itself.
