Also, the fact a lot of people write New Who doesn't automatically equal avoiding reading Old Who

I agree. I've written more New Who than Classic Who stories myself, but that's not because I like New Who better, because I really do love them both. In fact, as much as I love Ten, the Fourth Doctor is still my favorite Doctor to watch on-screen, and probably always will be. I just don't tend to write him. I think it's because the Classic stories are more iconic in my head, so I have a harder time writing fanfic around them -- the new stuff is easier for me to mess with, or perhaps it's more inspiring just because it's fresh.

But, I have noticed that when I do write a Classic Who story, it tends to get less hits than when I write a New Who story. That's what I meant about Teaspoon readers mostly preferring New Who. It's not anything against them; just a trend that I've noticed.
