Well running them all is easy, I mainly use Docker for running them, which makes it easy.
I just hope all platforms will be developed to maturity, and they will all follow the activitypub standards so they can communicate with each other. Now, some platforms implement features a bit differently from eachother.
Currently a 2 cpu 4GB VPS at Hetzner, costing 5 EUR per month. With a storage volume of also 5 per month. I am monitoring this and will scale when needed.
For mastodon.world we scaled it to a dedicated server with 32 cores and 256GB so we can go a long way.
You're welcome.. I've been using computers for around 40 years now, and love trying out new software.
That evolved in trying out self-hosted software.. even into self-hosting nearly everything.
I'm reverting some of that at the moment, don't want to self-host family stuff anymore because of continuity, but the rest I keep installing and trying everyting.. :-)
At the moment, I run lemmy.world using the funding of mastodon.world.
If Lemmy.world might grow and need a dedicated server, I'll try to raise funds for it separately (or create a larger .world fundraiser as I have other instances as well)
When creating a community, it would be nice if you also upload an icon and banner. Please make sure you don't use copyrighted images but instead create your own or look for rights-free material.
I don't know how communities are added. Is it automatically discovered or only when searched or viewed by users?
The search should be much better now I fixed an nginx issue. When I search for Mastodon I get loads of results, including the community at lemmy.ml.
But searching by community name !mastodon@lemmy.ml doesn't work. Sometimes it works when you click search a few times, sometimes not at all.
I'll discuss that with the Lemmy admin Matrix channel later, now it's time for bed..
I think my server lemmy.world would qualify :-)
