So I've been selfhosting git forge, dashboard, and OCW courses and I don't think I need any more services in life. I only have account in discord (for gaming), github, facebook (planning to get rid of), anilist (meh its just there), tailscale, stremio, and google. That's it, total of 7. I have not found use of any sass software, social media or any free tier of login software (except mentioned above). I also switched my notetaking method, instead of being dependent on something huge like obsidian (better than notion), I have a pkm lsp (markdown-oxide) with a spellchecker (harper-ls) and thats it. All offline, no data needed or sent anywhere.
I believe many people will be happy to selfhost but they just don't know :)
