JenSense reports that the Google AdSense team has added text link, in addition to its graphic ads, as an alternative option for sending AdSense/AdWords referrals to Google. It works the same way, you paste a snippet of JavaScript code on your page, and presto, you have the text link. It may look and work like the link directly below.
The forums are enjoying it, and discussing it. One of the members at WebmasterWorld noted the AdWords text link has a typo. Notice it?
I am surprised it is not fixed yet...
