I thought Whovian was widely adopted too, although I was aware it was initially only American fans who used it. My bugbears are the use of 'arc' to describe pre-2005 stories and the numbering of the Doctors with cardinal rather than ordinal numbers. I am ashamed to admit that both of these annoy me much more than they really should, especially the latter. I suppose it's all gatekeeping on my part and feeling that fandom has changed and I need to find a new role within it. (Sorry, looking back at what you actually wrote, I think I went off on a tangent there.)
