Facebook's announcements on F8 (read here) clearly are yet another sign that there is a lot going on in the battle between the top online properties. It's about the internet user (yes, about eyeballs too) and about ad revenue. In fact, it's about domination on the WWW.
What do you think Zuckerberg really said when stating yesterday that the purpose was to “make Facebook the centre of the increasingly social and more personalised experience that people encounter when they use the Internet” and that it wants to enable other websites and online applications to share information across the user base of Facebook (that counts 400 million people…).
What he really said was “the battle is really open now, Google”. And it's all about us: the "users".
