This was sent to me by a few people who know my fondness for crafting tin foil hats to protect myself from the all-seeing eye of Google.

The [full comic is worth a read as well](http://xkcd.com/792/). It's possibly true that the puppetmaster has no evil intentions, but that doesn't mean that we should continue to give anyone power over all of our online presences.
On a related note, an old project on campus was recently resurrected. We took a look at the code and data, and discovered that whoever built it had designed it to store passwords in the database as unencrypted plaintext. On a lark, I tried some of the passwords against the corresponding email accounts. About a third of them worked there, too... (the app is being rebuilt by a third party consultant, after we nuke the unencrypted data so it's safe to send to the new programmers).
