User blog comment:Craiglpalmer/Wikia is now Fandom powered by Wikia/@comment-5238398-20160926164854/@comment-26437440-20160926180918

"The name Fandom best represents the majority of the platform. Plus, the way we see it, the term fandom is applicable to any passion or interest that fosters avid enthusiasm and community. That certainly applies to almost every wiki here."

It makes sense for games, TV series, etc sure, but 'fandom' sounds pretty strange when used with most non-entertainment topics. Like SubarrowEvelyn said above, fandom doesn't make much sense in relation to a wiki about gas masks for example.
