The issue I see, and some folks may remember this, is that RK came charging into the forums somewhat like a bull in a china shop. I remember the original RK tractor guy bumping a bunch of threads with links to RK, to the point of being spammy. It wasn't until after TBN management worked with RK that a more reasonable presence was established on the forums. It was pretty good for a while, but declined and from there I think the presence was inconsistent at best.
RK brought all this on themselves if you ask me. You can't attempt to reap the benefits of being on TBN without accepting the challenges, and one of those challenges is establishing a long term stable strategy. RK wouldn't be the first company to dive into social media and then botch it up. Whether it's due to personnel or employment issues, doesn't matter, somebody at RK needs to be responsible for their online presence that they started in the first place.
