Several interesting notes have come in about Google entering the registrar business. One astute reader pointed out that Google already has a business unit targeting the domain name industry: Google Adsense for Domains.

From the Google page: "AdSense for domains allows domain name registrars and large domain name holders to unlock the value in their parked page inventory. AdSense for domains delivers targeted, conceptually related keywords and advertisements to parked domain name pages by using Google's semantic technology to 'understand' the meaning of each domain name. Powering over 3 million domain names, AdSense for domains is the industry's leading parked page service."
