https://fedi.video is a useful resource.

I've already added !andybalaam_lectures@diode.zone and !doc@peertube.biz to PieFed.

(Lemmy users may be interested to know that the Tesseract frontend also embeds the videos)

• @thelinuxexperiment@tilvids.com is pretty neat. I like his reviews and news in the space.
• @jeffjagoe@beetoons.tv I like the non-smash bros content they pop out once in a while.
• @veronicaexplains@tinkerbetter.tube She has some awesome linux and linux specific content. We watch her content over at our local makerspace when she has new videos.
• tilvids.com/videos/overview - Awesome instance with great channels. Also one of the best support structures ive seen for peertube.
• @coolmancoffeedan@beetoons.tv - Some strange stuff, but mostly uplifting? I think?
