Backboard, a sophisticated online solution for gathering feedback about various types of documents, came out of public beta this morning. Backboard allows users to upload and comment on standard Word, Excel, and PowerPoint documents, but it also supports most standard graphics formats, including PhotoShop, and gives users the ability to mark up and comment on web pages. Backboard is geared towards a wide range of users, including freelancers as well as enterprise customers, and it is one of the easiest to use feedback and approval systems we have seen in a long time.
