nortonham unicorn i don't know any specific site or youtube channel dedicated to netbsd. There are videos on youtube of installation run throughs and how to setup (for example) xfce.
unicorn I use USB tethering to connect to the internet, but with this method FreeBSD often lags. I can't tolerate it, but it's fine with NetBSD and OpenBSD. I want to use NetBSD as my main os. I want to learn more about NetBSD. I can't visit Youtube, and in the NetBSD gallery are mostly articles.
puhaTek Unicorn, if you can get hexchat working you can use IRC. #netbsd or IRCNet has quite a few users on it. logix managed to help me get my NetBSD box connected to the internet by using my Raspberry Pi 3B+ as a Wifi router via a ethernet connection.
dressupgeekout For whatever it's worth, I am planning on making NetBSD content on my YouTube channel. (Long-term plan.) And I'd be willing to host them elsewhere, too -- since I guess YouTube isn't an option for you and perhaps many other people.
