Hmm...if I had a page of my own I'd probably upload my custom designs for hyprland, random tutorials and/or random quotes (maybe you could make a presentation card, handy to show people movies/music/books or stuff you like without having to recall them). I don't know how setting up a page works but maybe a signing board so people can leave a little comment :p (this last one might be more difficult/a headache because of random trolls)

Pd: Haven't set up a webpage myself because I'm not informed enough on it, so I'm speaking without experience. But go wild! :p
