The hardest thing about lemmy was signing up and figuring out how to access it and log my account into mlem but things are mostly smooth after that sure there are some bugs but i feel like i am learning quickly
The only big disadvantage i see in lemmy other than the sign up process is the lack of a dedicated video player but it’s understandable because they cost too much to maintain and run
History matters : he makes short 3-4 minute videos about interesting historical topics also his 10 minute history series was amazing I highly recommend it
Since you liked pointless hub you should check out alternate history hub it’s owned by the same guy and his what if scenarios are amazing
