I started off by checking to see if fandoms I was ambivalent about had a lot of volunteers, and most of them did. And then I thought: Wow, I am so much more excited about Fandoms A,B, and C than Fandoms D, E, and F that ... I am going to strike D, E, and F anyway. And then I checked them just to be sure, and they had more volunteers than requests even without me. Win/win!
