Lately, I've been speaking a lot about trade-offs in web content management technology. Historically, one important debate has transpired between developers of website management tools versus "purer" content management products. A few years ago the pendulum was swinging towards the latter, as companies wanted to publish authoritative content to multiple channels and avoid performance and other problems associated with dynamic delivery. Now, a new emphasis on "Web 2.0" patterns seems to be accellerating a shift we began to notice early last year back towards an interest in website management, and (perhaps more importantly) greater managerial control over runtime interactivity, ideally through the same CMS interface. So now we see Ektron -- a CMS vendor that unapologetically couples content management and delivery -- come out with a new version of their flagship CMS400.NET product with even more interactive features, including forums, blogs, and analytics. Of course, there are tiers in the CMS marketplace, and at upper levels, enterprises typically don't want to put all their eggs in one basket this way. But as a buyer, you have important choices here...
