Blekko used to be a very promising search engine that aimed at adding more quality to search results by allowing searchers to use so called slashtags to their search. With the slashtags, search results could be limited to lets say a conservative viewpoint, or a liberal viewpoint, or whatever slashtag one like to use.
In addition, Blekko was able to return RSS feeds that could be loaded on to the Bookmarks toolbar as a very simple personal monitoring system.
The mobile sister of Blekko was IZIK search which too, had quite a different approach to search.
Both Blekko and IZIK are now postponed and owned by IBM Watson Group
