Earlier this week CMS vendor Hannon Hill announced the launch of "CMS Tube," a site providing video and podcasts about their product, Cascade Server. The idea is to help current and prospective customers learn more about the product via demos, training and education, with commentary and discussions with other users as well. Similar resources have also sprung up around open source projects, such as Drupal and Plone. But Hannon Hill, a smallish company of just over 30 employees, hired a media producer to run CMS Tube. I'm not surprised by this, however, given a growing trend towards building user communities, but at first blush, this site is all one-way: no comments, no tags, no user-uploaded media. Also, video is scant substitute for being able to reach a real person when you need one, so don't consider VendorTube a substitute for your support contract, but it can provide a useful supplement.
