Thanks, article seems interesting but "news feed" was an innovation that came in after the steady success of facebook (profiles, friends etc..etc.. that went viral over a tightly knit social crowd and spread from there).. Incremental innovations are what I see can get a startup in the rankings.. I found duckduckgo is really cool but still wouldn't appeal to the general population but blekko seems interesting..
