The internet changes day by day, and most people prefer "live" places like Facebook now where they can chat pretty much in real time with like-minded people. Forums in general, with their slower pace, don't give the same instant gratification that Twitter, Facebook, and Google+ offer.
So while we do get tens of thousands of people reading our threads, and learning, most then choose to have their discussions on the topic with friends in those live settings.
The world is always changing
. To wish it to stay the same is fairly fruitless!
