@Fragglemuppet Twitter's character limit and slower uptake among friends meant I followed people in a more interest-based way - lots of writers and artists. Facebook being under real names, I avoided public content and mostly went to share with my own crowd.
I've nudged some artsy friends to try fedi and they all report much more engagement in the fediverse - no surprise, since all the views/impressions aren't from bots! I'll keep dripping the idea on the rest.
