Google Announces Spring Cleaning

You have to admire their spunk.  And funds.  They have tried a number of unusual efforts and dared us to use them.  Announced, a list things that are being sunsetted.  Notable to me was Wave, who's AI implications intrigued me.  I even sketched out a potential enterprise use.  Notable too was Buzz which promised some additional social social communication channels.  Knol was an idea far too late and not quite slick enough.   Gears I examined but did not have any direct use for.   The link above has lots more, including in some cases external replacements for some of these tools.
