My two cents while trying to avoid too well-known outlets:

>YouTube channels:

Forgotten Weapons (world-class firearms history)

The Tim Traveller (general European infrastructure et al history)

Project Farm (one-man Consumer Reports-esque testing)

MedCram (excellent in-depth scientific but accessible medical information)

Tasting History with Max Miller (culinary history)

Two Minute Papers (covers recent scientific papers; rather tech-related but I see no other coverage of most of the stuff he touches on)

U.S. Department of State (the press briefings are immensely insightful and not a circus like the White House equivalents)

>Other:

Standard Ebooks (if its in the public domain and somebody bothered to professionally process it, it's probably worth reading!)

Father Stephen de Young's The Whole Counsel of God Biblical lectures (In my opinion, easily the best English-language dissection of the Bible ever written or recorded. Presented from an Orthodox perspective but frankly immensely useful for anyone interested in the Bible generally.) (Also, not to be confused with his related but separate blog of the same name.)

Drudge Report (obviously a hard right bias, but nevertheless more insightful than most mainstream publications, plus the formatting is such that you can digest a day's news in 30 seconds from skimming around the page)

Middle East Eye (a rare seemingly independent middle east media outlet. Broadly left-wing bias.)

4chan (quite frankly, while there is a lot of noise, there's also signal buried in there that simply isn't possible with other mediums. For example, the photography board's current film thread: https://boards.4channel.org/p/thread/3971021 )
