There’s an entrepreneurial lesson in the current Facebook dustup:  hubris can quickly lead to trouble.

There’s a fine line between confidence and arrogance.  Confident companies know what they’re going to do, and they do it.  Arrogant companies take it a step further and make it about proving something.

Arrogance is trouble because it kills the fan base.  Companies and entrepreneurs, like sports teams and rock bands, need fans to be successful.  Even famously arrogant companies like Google and Wal-Mart treat their user-customers well, and when they mess up, they usually attempt to make it right.

Facebook is in the middle of pissing off all the fans.
