As I stated about a year ago in a WSO conversation about Groupon and Living Social, there are virtually no barriers to entry in this marketplace. I just signed up for Google Offers in Washington, D.C. and the delivery system, visual platform and quality and quantity of offers blows away the competition. Google whiffed on Google + but with Google cloud computing, Gmail, Google Offers, Droids, etc. it looks like Google really does have the highest quality personnel in the business. It's an impressive company.
