Seesmic is best known as a Twitter client but the company is moving in an interesting direction by turning its desktop software into a platform that enables users to publish to many platforms, not just Twitter, but to Facebook, LinkedIn, and more.

It’s a great move, because we need tools where we can create content in one screen and decide where to publish it.

Seesmic will release a software development kit that allows developers to create plug ins for its software that support many different services. And developers can customize the software for specific applications or for branding purposes.

The new strategy also removes Seesmic somewhat from the constant threat of Twitter competing with its developers.

Here is Loic Le Meur, CEO of Seesmic, talking with Robert Scoble about the new Seesmic desktop software.
