I have a suggestion for Linus, "himself" and maybe others that he works with at LTT.
How about a channel that helps it's viewers to comprehend the world of IT business and podcasting from Linus's point of view?
Revealing the "behind the scenes", mindset and decision making that companies go through that LTT viewers are unaware of.
Another idea i had that LTT should do, is a charity run to support groups that protect the health of the internet.
The foundation that rests on the shoulders of all of our interests is is that of the internet at large, which is in dire need of your attention!
Maybe for every view count that Linus Tech Tips receives on YouTube, a dollar is given to an organization for 1 year.
I think your viewership would get onboard with this idea as a way that they could easily contribute,
without needing their parents credit card to shape the future internet.
Example of organizations:
openmedia.org
https://www.eff.org/
FireFox,
Wikipedia,
etc.
