My two cents: I may love the things I request for Yuletide, but they aren't necessarily my favourite fandoms. There's more to "fandom" than just loving the text/canon, and part of that is community, ongoing interaction, ease of engagement, etc. I have other things I do all year, other things I may enjoy more. Yuletide is a lobster dinner, but when I get home from work I like to eat mac and cheese.
