The document discusses options for MySpace to adopt, including using their own proprietary platform or adopting the OpenSocial platform. Adopting OpenSocial would allow MySpace to quickly match Facebook's functionality at a lower cost without major modifications, but may reduce differentiation. Developing their own platform could allow more control but would be more costly and risky. Overall, adopting OpenSocial is presented as the best option for MySpace as it would reduce costs, match Facebook, and be user and developer friendly.
