Forrester reseched a couple of blogengines; Blogging Platforms, Q2 2006
Forrester evaluated leading blogging platforms across 54 criteria and found that iUpload leads the market with its robust blogging capabilities and its strong strategic vision of a blog as a lightweight content management system (CMS), a collaboration and knowledge management tool, and even as a foundation to form communities of customers. When choosing between a full-featured suite like iUpload's Customer Conversation System or strong blogging-focused solutions like Movable Type and WordPress, companies should have a well-developed vision of how blogging will be used within the enterprise and then select a vendor that shares that vision.
Typical. They see Drupal as a Blog Platform a "lightweight CMS", probably because corporate blogging is hip. Well, Drupal is not a blog platform; its a Content managemnet Platform, you can use it for way more then just to run a blog. Somehow, I dont think they will sell lots of copies for this "research", "Price: US$1995.00, Report Length: 15 pages".
