When Feedster was alive and well last year I used it a lot. Today it has been reborn, but it is definitely a shell of it’s former self. Trying some standard search terms I follow resulted in what I would consider semi-relevant search results.
They have a cute widget to put on ones website and it nice and fancy but the search results have spam blogs in them all I want is the RSS feeds. Forget the widgets. Plus most of my custom searches are for my eyes only not the general public.
While I do not know the politics of who is behind the site and given the history with the previous company only time will tell if they will be able to ever compete with Google Blog Search or Technorati. Feedster
