The coronas of Twitter and commerce have overlapped, and local businesses are glowing with the prospect of new business. Witness the success of the New Orleans pizza shop Naked Pizza. According to Advertising Age, it ran a test Twitter-only promotion on April 23rd, and experienced a 15 percent bump in business for the day.
This could also be viewed as a sign that Twitter is about to jump the shark. A recommendation from a trusted friend is the most powerful form of marketing, and at the moment many of us who Twitter tend to think of other Twits as part of an extended family. Ergo, a special offer via Twitter enjoys the benefit of that bonhomie. Because of this, you should expect a deluge of companies attempting to convince you to follow them so you can receive "special deals." Be suspicious. Be very suspicious.
