Microsoft is interested in Facebook - as it Google - but Microsoft is putting its money where its mouth is with a 240 million dollar investment in the company.
Why is Microsoft, or Google, or anyone else interested in Facebook?
Facebook's value is not in the software itself—which could be duplicated relatively easily by a small group of programmers—but in the vast social networks the site has gathered, networks that contain information about people's interests and desires that would be invaluable for any marketing company.
So be careful what you put up there folks. This one social network that is going to become an advertising network in the near future, and if that isn't enough to stop you putting confidential information up there how about the identity theft risk that sites like Facebook pose.
