I've made my way through the ranks of IT over the last 20+ years and have seen a lot of technologies and websites come and go.
This is just my thoughts on what happened to "Forums". They died when better UX/UI was obtained through faster innovation from the likes of Facebook and Twitter which really took off in the last 5-6 years. Only die hard forum fans still hang on to these forum web sites. Website forums are just a dinosaur of a technology, like any text-only website reviews for products. The main reason I'm here today is because of the forum database attack I was not notified about by VerticalScope. I had to find out from another member and that's crappy on its own.
No one can argue with the money Youtubers are making; In 2016, the kids are not reading web pages like we did in 2000. Now they are going to youtube or similar, and they want to watch a video of the product and get a better feel for it all around. This goes for every thing marketable. This is why print media has been getting sucked in a vacuum and performing the longest slow death in history. Personally I do pay for my motorcycle magazines and continue to support them, but I would also be just fine if it came as only a PDF to my tablet. Having the magazines collecting dust around the house only introduces wife-aggro.
Also the answer to making the ZX-14 better is the H2. Kawasaki broke the mold yet again.
