For sure have seen this, but I also notice boosts of new users saying "Hi, I'm new here," receiving lots of welcomes, feditips, hashtags, etc., alongside posts from newer folks saying how much they love it here.
It's not just 'techy' people either. I've seen knitters find a home here, while some tech folks go 'meh' and leave.
Would be useful to understand the difference in initial experiences that tips it one way or the other to help improve onboarding.
