Flutterby™! : control of content

In her January 7^th entry (apparently it's not in the archive system yet so I can't link to it directly), Debra Hyde laments that Bdsm.about.com requires AdultCheck for access, which makes some of the articles no longer freely accessible. One of the reasons I like the "weblog" model of web publishing is that control of the articles remains with the original author. Of course this means each author has to figure their own revenue model, and without some sort of personal archiving infrastructure, akin to a bookshelf or personal library for our dead-trees content, we're out of luck if our favorite publication decides to change policies later. No answers, but a few questions.
