MySpace is finally ready to launch its OpenSocial-based development platform. According to Mashable, developers can now submit applications for review and the first set of approved applications will be available to users on March 13! In January, I talked about MySpace and OpenSocial in one of my previous post Facebook Platform vs. OpenSocial. Although it was announced last November, Google's OpenSocial partners are only starting to launch their platform initiatives with 3 large sites (MySpace, Google's Orkut and Hi5) launching over the next month! MySpace's Jim Benedetto did a great job at the O'Reilly Graphing Social Patterns conference outlining MySpace's upcoming platform's strategy.

When Facebook launched its f8 application platform it experienced a 37% increase in growth and the number of available application quickly grew to over 10,000 by the end of year. It is going to be interesting to watch MySpace's OpenSocial platform roll out as far as the number of applications being developed and if they do indeed bring users back to the site.
