We are all probably aware that, as of yesterday, Google had "refined" the way they keep track of where we are going on the web in ways we hadn't even envisioned. Their memory of where we have gone is sooo much better than our own.
For a nice summary of the sometimes surreptitious ways they, and others, have kept track of us, give a listen here.
For some ways to maybe counterbalance the surveillance, try these. Maybe Google Dashboard will become your favorite stop.
