I wonder how much disk space the big instances are using... I'm only at a dozen users. I have subscribed to most of the largest communities across the "threadiverse" so my instance is caching a copy of everything happening across those. I'm under 2GB space used so far.
I imagine it's mostly the media uploads. I think that doesn't get cached, just the text. But anything a user uploads will get saved to their instance's storage. I think.
Indeed - today something finally toppled in the internet realms. I felt it, and I created my first instance and joined. I'm sure many others will to.
I even ran into a few difficulties setting up my instance not yet documented but added a few comments to the relevant github threads. It's happening, and fast.
