StartupFollower lets you select startups to follow using a find-as-you-type form hooked into the CrunchBase API. When TechCrunch writes about any of the startups you're following, you get an email digest with all the relevant posts from that day.
StartupFollower is just an alpha/experiment; it was built in about 6 hours.
