A search engine modeled after Wikipedia was launched today.  Instead of relying on fully-automated searches, Blekko will depend on human input to develop, modify and edit search options.   

Search results are divided into seven categories that represent the highest volume of search traffic: health, colleges, autos, personal finance, lyrics, recipes, and hotels, according to the Blekko website.

Under construction for the past three years and designed as an alternative to Bing and Google; Blekko.com, will take a turn at eliminating spam from search results on the internet with the open-search, user-based system.

"We realized we could make web tools that let users sign up and help make the search engine better," said Blekko chief executive Rich Skrenta . "If we opened up the process, we could not only get orders of magnitude more people involved than we could ever hope to employ, we could also create an open, accountable process around the search engine relevance data. "

Blekko will use live people to create slashtags, web pages generated into groups by specific topics.  The Blekko's website defines slashtags as tools that will search only the sites you want and cut out the spam sites.

"Bing and Google have hundreds of contractors that use web tools to refine this relevance data - classifying porn, spam, domain parks, e-commerce sites, fake 404's, markov-spam, official sites, and so on," Skrenta said.

Since its start in 2007, Blekko has secured $24 million to get the site up and running.  Their goal is to identify the 50 best sites on the internet in top search categories.  The site boasts 3,000 slashtags so far.
