My comment is more of a tangent along people/products but certainly I agree in that I don't see why the wider Wikimedia group of sites including things like Wikibooks needed to completely evict "fun" content, even if I personally don't think it should be in some language's Wikipedia itself.

Not least, you can crosslink between Wikimedia sites, so you could just link to [[fans:Digimon:Whatevermon]] and have the content "nearby" in digital terms without drawing it under the same notability and sourcing guidelines as an article on benzene, say.

Which as you say would keep the (often very, perhaps to a fault) keen contributor to the fandom in the Wikimedia tent and might encourage them to contribute to Wikipedia and related sites as well.

Then again, the auxiliary Wikimedia sites are pretty neglected by the parent foundation which has more important things on its mind much of the time, mostly fundraising and finding novel ways to spend that money.
