To developers, that is. Marc’s Voice reports that the second most closed (after a small world) of all SNS’s now has a full API open to developers.  There are, in typical Facebook style, plenty of requirements for anyone developing on the platform, but nevertheless, this is a bold move from the smart player we know Facebook to be.  Tons of developers will be stumbling over each other to innovate.

Such a contrast to the wall-raising going on at MySpace.

As a believer in open networks, I think this move will catapult Facebook in terms of innovation and quality of user experience.
