Check out Kyle's interview from this year's CMS Expo:

In Kyle's interview, he discusses CMS Market's unique offering - one unified directory for all Content Management System, where developers can list their extensions, modules, plugins, components, templates, themes, etc. These free listings are a perfect way to get your hard work in front of people that may not normally traverse the official Joomla!, Drupal, or WordPress directories. CMS Market is also unique in that developers can sell their digital goods if they don't already do so on their own site. Many developers develop extensions for clients that are extremely useful, but they aren't interested in running an online store or club. Those devs can quickly add their extension to CMS Market and either give them away are make an extra buck.

The CMS Market vision is to provide one unified marketplace where you can drink your coffee in the morning while checking out the latest digital goods from any CMS, all in one place. For many devs and clients, the CMS doesn't matter as much as the solution. CMS Market will make these peoples' lives easier.
