One of Posterous’ first “clients” is Coca-Cola, which is definitely a good first start. Coca-Cola is using Posterous for its NCAA “Dept of Fannovation” where people can come up with ideas to improve the experience of being a fan, and a chance to win $10,000.

Coca-Cola’s use of Posterous revolves around the “post moderation” feature. Any Posterous site can be enabled so that anyone can email post@sitename.posterous.com. The site owner can then moderate those posts, and publish them with a single click. This feature can be used to crowdsource images, video, and text from users.
