The linux motto to any problem is “it’s possible, but here are the pitfalls”. You can do almost everything on linux (unlike windows), but the tradeoff is it can sometimes require more time to learn and troubleshoot issues. In my opinion, linux is great for those of us who dislike to use the mouse and take our hands off the homerow. Get used to using the terminal to launch apps, instead of clicking stuff on the desktop. Learn keyboard shortcuts. My recommendation is to use a window manager like i3 with an i3 status bar at the bottom. This will give you a minimal desktop, where you can move windows/tiles around all with keyboard shortcuts. Open apps with something similar to dmenu, where you just have to press a keyboard shortcut and type the first few letters of the app you want to open, and press enter. Learn vim-like keyboard navigation to edit text and reposition the cursor through the text all without the keyboard. Linux integration with this style of experience is vastly superior to Windows and Mac.

OP, the answer is obviously to starve yourself and use a buttplug

I tried Joplin, but found it more cumbersome than just directly using markdown files, and rw them with Markor on Android. On Linux, I will just directly rw the markdown files in vim, or vscode if I want to get fancy.

This is actually good. Twitch has become just as anti-consumer as Reddit ever since Mixer shut down.
