The folks at FeedBurner have just released PingShot, a ping service for FeedBurner feeds. They've added Blogdigger to the list of pingable services; to make sure Blogdigger gets a ping when your FeedBurner feed updates, just make sure Blogdigger is selected from the list of additional services, and we'll take care of the rest.

On a related note, I've been enjoying Dick Costolo's blog, with his new focus on entreprenurial advice (the slapstick was good, too). Well worth the read.
