I’m not a web developer. I’m sort of a sysadmin so i have some experiences maintaining machines for web apps for other people. And you are right…text will not create massive amounts of data. But a lot of tiny transactions can bring down machines surprisingly fast even if the total amount of data is relatively small.
I guess we are here to experience it first hand. I don’t think anybody…not even the developers have a clear idea of how well this will scale. There is only one way to find out lol
I wouldn’t recommend hosting it from your home network. Even if you are only having a couple of buddies on there it could easily be ddosd by a post going viral or something. Also you would permanently leak your personal IP adress to the outside world. There are ways to protect yourself against that but it’s probably not worth the effort. You are better off just renting a cheap vps for your 50 person instance. You can rent those for like 5usd a month. Share that money with a handful of friends. Everyone puts 10 bucks in and you can pay upfront for multiple years.
