Wires has a write up on how the Google AdSense product made the lives of a small consulting firm, a complete mess. A company named AdSense Consulting, established back in the late 90s, owned AdSense.com and because of it, received hundreds of emails and phone calls with Google AdSense tech and customer support questions. A nightmare for a small company that has to field these calls all day. They recently moved to a new domain at adsense2.com, and have a redirect up at AdSense.com for those who want to click over. This has helped reduce the volume of support requests.
This is funny but yet upsetting to me. I wrote more about it at the SEW blog, and JenSense has her take here. Note that Google has the trademark for "AdSense" even though this company has been around a lot longer than the AdWords program. :)
