This morning we announced the public release of the TypePad Platform and APIs, which we hope will inspire a new generation of community tools such as TypePad Motion, a new open source microblogging application available today. You can  try TypePad Motion out for yourself or  go get the code and API access right now.

Since TypePad launched six years ago, Movable Type and TypePad have been sibling platforms that have developed in parallel. As of today, the opening of the TypePad Platform  means that Movable Type users and developers will be able to more easily take advantage of the new features and infrastructure improvements we're making to Typepad all the time.

We're excited to see the kinds of apps the community will develop using the TypePad APIs,  and we look forward to getting your feedback. Six Apart CEO Chris Alden posted about the significance of the TyepPad Platform  on the Six Apart blog today. Please have a look at his post for for a sense of his vision for Six Apart and for more detail about the Platform, the Developer Program, and TypePad Motion.
