I have run many personal servers. They all come and go. They get hacked. I lose interest. The content goes away forever, except if I'm lucky enough for it to get picked up in http://archive.org. Posthaven is like that, but you don't have to hope. It will get archived.

Self-hosting is great and I don't think we'll ever replace it. But for the vast majority of personal content out there, you want a caretaker. I hope you'll think of us when you do.
