Every day I find more sites using social media sharing tools such as AddThis. I love the idea - click on the little button and the link gets posted to Facebook, Twitter or Digg.
But, I am required to provide my sign-in credentials. There is no way that this is secure. Basically, I am providing my information to a third party and trusting them to do the right thing. But, they could be writing the usernames and passwords in a big database and giving that info to the NSA.
Am I missing something here?
