Microsoft Values Facebook, in more than one way

With the recent inquiry of investment by Microsoft into Facebook, the valuation of the company has exceeded 10 Billion dollars. Facebook has built an impressive platform and business model. Using a business model that allows a SaaS offering and at the same time opening it to the developer community to create applications to integrate with it. Similar to what Salesforce has done with AppExchange.

When it comes down to it, this business model is ideal for Web 2.0 companies as it allows the company to focus on what they do best, in Facebook's instance: social networking, and leaves the integration of other great services to the community.
