Pinterest is offering consumers a way to discover things on the web, in a serendipitous way, with a beautiful user interface. So it's offering a whole new paradigm called 'discover' and allowing users to be creative.

I don't want to use my creative energy on somebody else's user interface.

Facebook is becoming the web. Everything you need is there... it is the universe.

GUI (Graphical User Interface) is always intuitive to those who design it.

If you discover users who are misrepresenting themselves - for example, a user calling herself a student even though she is actually a member of the campus police force - please report this to us as soon as possible. The account will be removed.

Social media is here to stay, and the social phenomenon that is bringing this about is consumers' willingness to share more about themselves, share more about what they're doing... people are even willing to disclose where they're at. And this phenomenon is going to create huge commerce opportunities on the web.
