It wouldn’t be a replacement for that other site without:

• !ukcasual@lemmy.world
• !futurama@lemmy.world
• !lotrmemes@midwest.social
• !gamedev@lemmy.blahaj.zone
• !lemmy_stitch@sh.itjust.works

(those last two have posts with megalists of related communities too, for gamedev and crafts respectively, check them out if you’re interested in either topic)
