With the different layouts and themes, they can start selling themes like Tumblr has, creating a new market for that. This trend of Facebook taking other companies' ideas is evident from the hashtag being implemented into posts. Who knows, they might even try to take over Google's search function.
This looks pretty interesting, but, as everyone said, security sounds like it will be a huge issue.
Will there be other methods of verifying a user for email, now that it can be linked to your bank account?
