I'll paraphrase what I said before when we were going over wiki achievements. Extraneous features don't spawn greater activity levels. People will edit if they are interested in the content and have a desire to edit.

You can't spur that on with extraneous features. At least with achievements you could make the case that it's some kind of incentive and could otherwise be ignored, but message walls, blog-style forums and article comments not only provide no incentive, but are actually detrimental to anything more complex than a linear progression of thought.
