There are a few things I don't understand. It seems that a lot of websites are tracking behavior at toolness.org. Why? Is it reversed, i.e., the add-on from toolness.org is tracking these websites, or do these sites have sort of counter-measures to see when people use privacy tools? Can they actually read in information from non-https sites? Also, twitter seems to be tracking behavior on a number of sites. Is it because of those small twitter widgets everyone uses on these sites, or is twitter actually trying to collect data on what I like to browse?
