The /r/cms Subreddit

I continued to moderate the /r/cms subreddit. I’m trying to deepen the discussion, so I posted this question:

How do we differentiate between a “CMS” scenario as opposed to a more traditional “application” scenario?

[…] when confronted with a set of requirements, in what situations do you think, “I need to start with a CMS for this” and in what situations does a CMS never cross your mind as a foundation and instead you turn to a more general underlying framework (Symfony, Rails, ASP.NET MVC)?

There’s been some activity, but I’d like to see more, both for the sake of the community and because this is an important topic that could use some examination.
