Facebook hit 2 billion users this week. Reminder that FB was started in 2004 when Myspace was already killing the game.   How did Myspace get taken out? By not taking themselves out.   3 CORE TAKEAWAYS HERE: 1) Just because someone's already doing something doesn't mean you can't do it better. 2) Innovate yourself before anyone else beats you to the punch. Be your own greatest threat. 3) You're either chasing someone or being chased - either way, you better be running.
