Public Event Calendar site.

Bought by Yahoo in 2005.

You can submit an ICal feed for it to scrape, or push individual events to it via its API.

Shut down by Yahoo in 2013.

May'2014: Andy Baio ran a successful (asked for $30k, raised $100k) KickStarter campaign to relaunch it. My hope is to have a public beta by March 2015.
