I like your product, but I tried self-hosting it -- twice over maybe four years -- and both times it just fell apart and destroyed itself in about two months after being set up. Proper configuration and regular upgrades as recommended by documentation, afaict. I'm ready to admit that I'm a complete idiot, but I have never had anything like that with any other product. I have my own theories for why it keeps happening, but not having any proof will keep them to myself...
