Google is the one site my non geek friends truly admire, unconditionally. It continues to amaze me. I've been signed up with google adwords for quite some time, and have decided to test out AdSense. The first ad that appeared when I pasted in the requisite code was a PSA - they do that if they don't know your site content yet. Ten seconds later, when I reloaded, it was a targeted ad. Ten seconds! Whatever voodoo they've got going on is pretty kung-fu if you ask me (I wrote that to see if I get ads targeted to kung-fu and voodoo). All hail the oracle.
