A study by IDC revealed that most sites had customer loyalty rates in the low 30 percent range. You've seen one you've seen 'em all. Service, friends, service. Service can't be commoditized. It can't be copied just by hiring the software development away from your competition.
Good service requires infrastructure, management skills, training, and commitment.
Service can't be measured on a purely objective scale and reported on by a web bot. Most of all, service can't be shrink-wrapped and boxed and sold to your competition. Basing your web business on service entails more risk, higher capitalization, and a longer payout. You can't dabble. If you're going to go for it, you have to go full bore.
