Tinypug is a system for building portals that enables innovation communities. The idea is to go beyond one-off statistical surveys (which tend to only verify an existing paradigm) to foster real collaboration and anecdotal feedback from users/customers. A company seeking to gather more feedback on its products usually has to resort to a few existing stand-alone mechanisms such as polls and comments on product listings. But Tinypug puts all of these tools together in one place. It also makes it easier to integrate with call center applications for the active gathering of customer feedback. It's not a content management system as much as it is a feedback management system. It provides in-browser message boards, polls, surveys, and user-submitted ideas with voting. There's also a basic content system that enables you to upload and publish pages and images. You can customize the look of the site using themes and extend its functionality using add-on libraries.
