Yep. I was a plain old forum member for years first, but I'm a rung or two higher on the totem pole now.
Discussion with an author about their article? Yes, it would, can, and does.
As I mentioned earlier, there's nothing stopping anyone from starting a thread to discuss any article they'd like on the forum.
And, really, it kinda seems like some guys are glossing right over that simple solution, they still aren't starting those threads, and they're still complaining that "there's nowhere to discuss the articles." You don't need an "article discussion forum" to discuss articles.
Want to discuss Rippetoe's deadlift article? Start a thread in Powerlifting or BSL. Want to discuss Thib's Destroying Fat article? Start a thread in Thib's forum. Want to discuss today's back thickness article? Start a thread in BSL or bodybuilding. I get that things aren't the way they used to be, but things aren't all that complicated, either.
Also, Lonnie did just bring up some good points about some issues with keeping the article comments active. Facebook is largely becoming the go-to for discussing written pieces with most magazines and news/information outlets. The quality of those discussions, just like the quality of discussions here on the forum, will reflect its participants.
Like I said, we're working on getting coaches even more interactive all over, but many if not all coaches today have a page on Facebook that you should be able to tag for questions/follow-ups anyhow.
