The (very fine) cmf2006 conference in Denmark that ended yesterday was capped a Web Idol competition, where 5 Web CMS vendors competed head to head with 6-minute demos. Each vendor claimed their system was easy to use, but among them had 5 very different interfaces. Lesson: if you want "easy," you'd better articulate just what you think that is. Also of note was the coupled management-delivery architecture at work among all 5 contestants. In the mid-market, website management is certainly come in vogue -- but as we've outlined elsewhere, buyers need to understand the cost, security, and performance implications of putting a CMS in their delivery tier, especially for public-facing sites.
