@expertmanofficial Hey,

1. I'm a 2D artist mainly, using Krita on GNU/Linux and only open-source since 2009. I also use Blender, and I worked at the Blender Foundation on movies and producing training material. On my webcomic, I use mainly Krita, and Inkscape for the speech bubbles and texts, and I spice sometimes my complex backgrounds with Blender.

2. No idea about Nostr; I went and read its page on Wikipedia. First time I read about it.
