Google recruiting ad

For the first time , I saw a print ad from Google today. Though they were advertising for a relatively lowly Adwords position (lowly when compared to the more glamourous dev/PM jobs), it's still interesting to see Google jumping into the recruiting-ads fray. I would have thought that Google didn't need to advertise and that people would stream in - but perhaps that isn't happening. Or maybe Google is growing faster than it can handle.
The ad is cool though. :-)
