Blekko is known for their search engine that is heavily filtered to knock out spammy content.
The company has now launched a new web service named ROCKZi which is sort of a Pinterest but for news stories.
Users can submit news stories in different boards and vote on existing inclusions.
The user interface is currently rather tacky and the overall experience is rather slow.
It is not clear what they are trying to achieve launching yet another social news aggregation platform.
