Anttenna

The annoyingly named Anttenna is based on a great idea for this decade of the smartphone wars:

Anttenna is a free mobile application that facilitates real-time, location-based, person-to-person exchanges. By turning traditional classified listings into geo-tagged twitter sized microlistings, Anttenna lets you quickly connect with people nearby. Got an extra ticket? Need an extra ticket? Lost your dog? Having a yard sale or an open house? Just post a quick mobile microlisting.

Given the primary meta trends driving business success for this decade (including FREE, HYPERLOCAL, REAL-TIME, SOCIAL), then Anttenna has a real shot at becoming a major force -- provided it can effectively develop the appropriate ecosystem.
