yes! structural engineer here, computers has been my passion for a long time and self hosting is a joy! i have learnt a ton in the past year about networking, security and so many things!
Public services: my social network(hubzilla), Email(mailcow), Matrix chat, Peertube.
Private: my media (jellyfin, audiobookshelf, calibre, homeassistant.
I enjoy the freedom that comes with this and its like having your own home on the internet. I have a very modest setup but its enough to host my friends and family so nothing fancy like k8s. Just a refurbished optiplex running docker :)
thats a possibility, that is why either you sign up with a provider you trust or run your own server. that is the appeal of distributed network.
