Interesting, I have had my share of funny moments reading reddit but never felt compelled to post, either because I felt my opinions wouldn’t add to the conversation, but mostly because I compared it more with slashdot than twitter.
Here I’m much less intimidated about exchanging with others, people are genuine, collaborative and respectful.
As to your point of “content vs personalities”, I agree, but I also find this to be true here. I never interacted with cats, frogs, and whatnot before joining #nostr :)
