Great survey.

Their question as to whether blogging is "too easy" really resonates with me: I began prototyping a CMS a while back on the premise that Blogging Should Be Harder (a reaction of sorts, I guess, to services like Posterous and Tumblr [full disclosure: I am a very happy user of the latter]). And what I found is that if it's hard to design a "blogazine"--manually setting type and choosing colors for each individual post--it's just as challenging to build an "anything goes" CMS.

I still think it's a great idea. There might only be a handful of people out there who would use it, but those that did would likely be producing really top-notch content.
