Plancast – Social location planning.

Plancast — a service that lets you share future plans with friends, and view those from others — just got a whole lot more useful today. The company announced its API (application programming interface), which gives developers the ability to use Plancast’s data in their apps, reports the technology blog TechCrunch.
The service is best described as “Foursquare for the future.” Instead of telling people where you are, you can broadcast what you’re going to be doing at any given point in the future. It’s similar to a shared calendar, except it offers up a social graph like Twitter or Foursquare. You have the ability to follow people you’re interested in, and you can also lock down your profile to select readers. Not surprisingly, Plancast is looking to integrate with calendar services like Google Calendar. It also recently added the option to import events from Facebook.
