> There is a big flaw in using browser information as an identification token in this way as browsers change. > I visit this site at least once a month and every time it picks me as 'unique'. That is because each time i've either installed a plugin, installed a font, my browser version changes every 5 days with automatic updates, installed a new browser, installed a different browser, am using multiple browsers, am accessing from my phone, ipad, work computer, etc. > This makes it useless for actually tracking people. Not at all. This site isn't a demonstration of tracking you, it's simply a measure of how unique your browser is. Somebody who actually cared about tracking you could trivially track changes: a profile with a set of 191 particular fonts and a later profile that is identical but with 190 fonts is probably the same person.
