It's all about Twitter today...but Zappo's is doing something cool -

Check out this novel use of Twitter by Zappo's - it showcases flattering and not-so-flattering mentions of Zappo's in the twit-o-sphere, aggregates Zappo's employee tweets, and dedicates a stand-alone page to a visual gallery of tweeting Zappo's employees (pictured below), force-ranked by the total friends/followers they have.

That last twist means significant competition to be #1 - so Zappo's employees are effectively pressured (in a fun, socially competitive way) to spread the Zappo's marketing message and brand experience. 

Now that's neat.
