There's also some initiatives towards the use of human editors and contributions from the social community and media. These alternatives do present their own advantages, as results from these search engines take advantage of human expertise as well as the wisdom of crowds. However, they lack the depth and scale provided by the major algorithmic search engines.
So why not get the best of both worlds? FuzzFind Web Search is a web search mashup that combines the best of the major search engines (Google, Yahoo Search, Windows Live Search) and social bookmarking sites (del.icio.us)What's more, why not mix and match the best results from each of these sources according to your preference? You can change the 'recipe' of the search by adjusting slider bars.
Try it, you may be pleasantly surprised by the results.
