EFF Launches Panopticlick 2.0 (eff.org)

In addition to measuring whether your browser exposes unique — and therefore trackable — settings and configuration to websites, the site can now test if you have correctly configured ad- and tracker-blocking software. Think you have correctly configured tracker-blocking software? Visit Panopticlick to test if you got it right.
2 interesting things about panopticlick: first, they report on browser fingerprinting, which is notoriously hard to defeat. second, they encourage users to allow ads from websites that purport to respect Do Not Track. there's no way to know if they actually respect it, and companies like google and facebook have been bald face liars in saying they respect it when they actually don't.
