> If you were giving presentations you'd get questions and comments at the end. Since a blog is typically read/delivered in async fashion distributed across regions the only feedback you get is via analytics

If only there were a way for readers to post questions or comments back to the authors of blog posts, there could be feedback without the indirection of analytics. Too bad no one has, in the history of (either standard- or micro-) blogging thought to provide such a mechanism.

Comments like this (snarky, posted behind a pseudonym) are generally why I turn off comments on my blogs and rely on analytics :)
