I haven't seen much discussion related to any new fandoms, but I wonder if that's more to do with the fact that shows come out all at once instead of week by week. That format gave me more time to reflect and also read meta posts.

I think that changes in TV production has made a big difference. It's not just the episode release schedule but the shorter seasons and the bigger (and more unpredictable) gaps between seasons and the greater volume of shows. All of these encourage people to move on rather than stop and reflect. And it makes it harder for a fandom to gather and grow all at one time. I mean some fandoms explode regardless (look at Good Omens last year), but I think it means a lot more small fandoms.

Merlin, of course, came early enough to avoid a lot of that and it has certainly proved to be a large active fandom. So yes, I find the lack of meta mystifying, though I think it also reflects the difficulty of finding it on sites like Tumblr and the breakdown in community functions when many social media platforms don't enable it.

And yes it is. Here you go :)
