Since I got Google AdSense, I enjoyed watching a small pile of money build up.  It wasn't much but it was enough to offset my webhosting expenses.  Thanks to the Gag clause recently added to AdSense T&C by Google, I removed AdSense from this blog.  According to AdSense FAQ, this effectively cancels the account.

I agree.
