Last week we witnessed the unprecedented passing of three pop culture icons; Ed McMahon, Farrah Fawcett and of course, Michael Jackson. Each left a lasting impact on our hearts and minds and their deaths within a few hours of each other caused unprecedented demand on Twitter and other communications and social networking sites and services. This week we pay our respects to those pop culture icons by identifying emerging companies that help you track pop culture and the conversations taking place about it.COLLECTA (http://www.collecta.com/) came on the scene just a couple of weeks ago, but it seems to be making quite an impact.
