I've been finding fandom a slightly frustrating word lately. I hang out in the intersect of transformative works fandom and SFF book fandom, and both sides want to claim the word fandom for themselves without acknowledging the group and its strange and gets to me more than it should. So hanging out on the internet and talking about books feels like fandom to me, creating transformative works feels like fandom, have conversations about how the worldbuilding even works feels like fandom, going to cons feels like fandom, sharing recs for works fan-or-otherwise feels like fandom. But whether a given speaker things any or all of those things are part of fandom is unclear and it's annoyingly hard to know what people are talking about.
