So if a startup can build a product leverage facebook's network effects which falls outside of facebook's stated mission but can serve to keep users glued to the site it can do something of value that Facebook is unlikely to replicate.
For example see MosoTo - they are doing things on facebook that facebook aren't doing because it falls outside of its stated mission and so would be deemed a deviation from its product (chat + photo and media sharing).
For Facebook hackers out there - heres the rationale for building valuable products off of the facebook platform.
Like its been said before, startups that rely on other networks without explicit agreement are calling for trouble.
How can a new startup bring unique value that facebook couldn't just duplicate with a few outsourced coders overnight?
