Compare it with facebook

Facebook and Twitter actually look like pretty different products and businesses today. Twitter is a broadcast/conversation communication platform, while Facebook is an identity platform with communication and distribution, and financial applications built on top of it. Unless Twitter gives users more Facebook-like control over different parts of their identity, Twitter is going to have a hard time serving those users who are more sensitive to security in addition to those aiming for more visibility.
