Yes, but I find it interesting to see that despite having a theme, slrpnk.net is as spread as generic instances and less clustered as, e.g. programming instances, lgbt, anime or nsfw ones.
I also find it interesting to see which communities bridge users from several instances: /c/ubuntu is the link between the french-speaking world and programming? /c/dragonball is the most mainstream anime community. I also find it interesting that the tankies communities, despite a few bridges, look extremely isolated.
Yes, except this is of all lemmy users, not just slrpnk.net, which is just one of the instances measured.
