Start-ups and big companies alike have tried to take on Google by building a better search engine. That they have failed has not stopped brave new entrants.
Rich Skrenta helped found Blekko, which he began working on in 2007, to help users find results from only trustworthy sites.
The latest is Blekko, a search engine that will open to the public on Monday.
Rich Skrenta, Blekko’s co-founder and chief executive, says that since Google started, the Web has been overrun by unhelpful sites full of links and keywords that push them to the top of Google’s search results but offer little relevant information. Blekko aims to show search results from only useful, trustworthy sites.
“The goal is to clean up Web search and get all the spam out of it,” Mr. Skrenta said.
