Does it even matter that it’s Mint in particular?
Yes somewhat because the devs of Linux Mint has created a reputable high quality First User’s Experience to Linux setup.
I’ve never used mint, but isn’t the DE (or WM if you abhor DEs) more important?
Somewhat yes but it’s mostly the combination of all the ingredients that can make or break the lasagna dish.
If we’re comparing the DEs with each other than Plasma would win hands down over Cinnamon but for introductory users looking to switch from Windows or Macs to Linux than DEs are less likely to be an immediate concern.
They all come with a package manager.
Linux Mint would use the APT package manager which is good for beginners as you’d be able to use the same troubleshooting steps as Ubuntu or Debian.
Except maybe Nix, from what I’ve heard
NixOS is complicated to say the least, in which I’ve previously discussed here
Good question and thanks for asking!
As far as I’m currently aware, due to YouTube constantly changing things, YT thumbnails often will not load unless directly linked to the video’s thumbnail (at least here on the Fediverse).
Because of this, it allows me to link to alternative sources within the post such as Invidious (YT alt ad-free frontend), Peertube, Bandcamp, etc.
