@inherentlee Different platforms can have different tagging standards for a variety of reasons. Seems like a good idea to adapt as necessary. I'm pretty insistent on using book-title-style capitalisation with AO3 tags because that's the standard. It annoys me when people do shouty allcaps or the Tumblr whisper space thing there. But AO3 allows for spaces in tags so caps style is less of an issue in terms of readability.
