I have one major issue with this change. If I'm watching videos on my computer its on YouTube, i don't want to have to another site just to see if one person I like to watch posted a video. It's too out of the way and how would I know when a video was up. Furthermore no i know nothing about how much Linus is paid but what I do know is that companies like Rooster Teeth are able to have 60+ people working with revenue gained from very similar ways that Linus does it. Yes I know they have way more subs and get paid more but the difference doesn't scale to way(from what I figure). The same thing can be seen on vimeo. There is a ton of amazing content on there but how many people use it? not that many? having people go to another website just for your videos wont work well and I'd be willing to bet that after this year is over the numbers on those videos will go down drastically.
That's just what I think and personally I hate this change. If i were to give suggestions its would be do a sponsor like thing on your own website and have people pay so much a month to get early access. Then the people who already use the forums a lot will prob pay for it cuz its not out of their way and you get paid more directly.
