facebook rights to content

what is most valuable about facebook, its content or the interface? ?
I asked this question and eliminated. (? Curious) So I think it-that the contents of text content in a form of another couple – the profile information, different types of comments. it contains the photo. see who has friends funness according to their own interface, the ease or experience. the clarity with which obtains the contents. This and other things r probly, right? as a "platform." facebook one day go public. one day (maybe much later) die facebook. but for now is very valuable. constiuent these parts can be separated? I can not wait they could. but yeah.
Perhaps the interface.
