Sproose -- An Alternative To Personalized Search - Watch today’s top amazing videos here

A bit about Sproose via their latest press release:

[...] Sproose uses a "human popularity voting" model where users can self- rank the index creating personalized search results. The more users that vote a site the further up in the ranking it goes.
[...]
Sproose provides a consumer search engine whereby the users can influence the ranking of the index by voting on the results. Each user is able to create a different set of search results when searching under the same keyword. With its proprietary 'Knowledge Rank' moderated directory technologies, Sproose users can effectively categorize and index sites, tailored for personal or group usage. The rating of search results is done without downloading applications to ensure privacy.

Another alternative to Personalized Search is the Swicki. These provide community driven results. Read all about that in my blog post Vertical Search 2.0: Can It Kill Personalized Search.
