The eBay auction for Kiko, the Web 2.0 calendar app that we reported was on the block last week, has ended. The final price was $258,100, offered by an eBay user called powerjoe1998, who will take home all rights to the Kiko software, web site, and domain name. Kiko team member Richard White has penned a very interesting post-mortem on the details of the service's demise which is a must-read for potential Web 2.0 entrepreneurs. Currently there's no word on what Kiko's new owner's plans are for the service.
