I hear you on Kate/Clint (or even Kate & Clint) being a small fandom. I did one in that fandom I am quite fond of (Diamonds and Rust), but only a handful of people read it so I just have to keep my fondness to myself. The one that is mostly about them but tagged Clint/Natasha did much better (although that, too, seems to be increasingly niche). Oh well.

But congrats on a prolific year! I think I read everything except Leverage (of which I know nothing) and the Star Trek one. Must have a look at the latter!
