I work for Tynt. I appreciate the discussion here and want to make sure that everyone knows we want to be respectful of the opinions here. Not sure i I will get flamed just for wading in, but I hope not.
To clarify on a few points
1. Tracking and Attribution – the attribution feature is separate from the tracking features. The tracking features work very much like any other analytics tool. We do not store any personally identifiable information, but we do want to help publishers learn what content people are choosing to preserve and promote. In addition, publishers can turn the attribution feature on or off on their sites. If you want to see what is actually collected - sign up for an account and look at the dashboard, you will see that we are tracking the content, not the user.
3. What if I don’t want this behavior? We are currently working on a global opt out for users who would rather not have Tynt monitor them. In the interim you can opt out on a site by site basis (i.e. the opt out for the SF Gate is here: http://www.sfgate.com/chronicle/faq.shtml#faq1.5%23ixzz0bxLIAbL7). More info on how to not have Tynt monitor you is available in our FAQs here: http://www1.tynt.com/faq-technical-topics#ixzz0bxGzIgPZ
but as pointed out in the comments here, NoScript is a very effective tool for this.
