I think it might be the case for some, but mostly I think that more people on Lemmy are less focused on themselves and personal anecdotes. More often I see people here reaching for cited resources to support what they’re saying instead of “Oh one time my Uncle’s friend’s cousin…”. It still happens here, but not nearly in the same capacity from what I’ve seen.
