Data Sharing - With or without your permission

The new Facebook saga is going to be bad for them.  The Wall Street Journal exposed data sharing even when you don't have a Facebook account, and even when you specifically say you don't want to share sensitive data.  This is going to get Congressional attention in a way that is unavoidable and will cause a reaction that will take Facebook, Google and whatever other companies they can identify in its wake.  On one like this, Congress says "do something" even if it is the wrong thing and likely over the top in its application.  Nobody will care this time.  Congress and the EU have tolerated more from social media than they would on almost any other group.  Facebook needs to get it in the neck over this one.
