In an previous post we covered two of the pioneering microblogging platforms, Twitter and Pownce. It was announced today that Pownce will be closing it’s doors after just one year of operation. Pownce was acquired by Six Apart developers of TypePad and Moveable Type.

If you are a current Pownce user, they have created an export service to transfer all your pownce posts to TypePad, WordPress or Vox.

December 15, 2008 will be the final day of service so make sure you get your posts out before then.
