I think a BDSM meta could be really, really helpful for anyone interested in but unsure of how to write it. Some people won't need it, but hopefully it would be of use to those who do.

You know chn_breathmint's guns & ammo tutorial? I didn't think I'd ever need it because I've never written an action scene into my handful of fics, but I started writing a scene that involved loaded guns at the ready and thought immediately of her tutorial, which was super informative! ...the focus of the scene eventually changed and went in a direction that didn't include the guns, but it was nice to know that it was there! =D

Maybe rimming as a hard kink depends on the fandom? 12 years ago in Gundam Wing fandom it wasn't as common as it is here/now, but... that was also 12 yrs ago...


ETA: dissociate just linked to Elements of Style by jeannedecarnin -- was that the one you were thinking of? Re-reading it, I can absolutely see why! She posted that back in September and I didn't remember it at all!
