The multiple instances thing confuses me too. That was my biggest stumbling block to even getting an account - I could not figure out how it worked to just get an account and get to see what I'm used to seeing on Reddit which is the various feeds of content. It initially looked like Discord or something which is not what I'm looking for.

I'm hoping there is more clarity on that for newbies in the future because I can't be the only person whose eyeballs rolled into the back of their head trying to understand.

I'm super new and still need to get the hang of the instance thing. For the experienced folks: is there not an aggregation of content between instances? I am hoping not to have to work to see content from different places. The aggregate views of Reddit for communities I subscribed to/front page was mostly where I lived.

Of course I'll try to understand and read up, just noting where things are not intuitive in a way that could prevent users from coming over.
