I think making the top alphabet section more accessible when scrolled down on the page would be the way to go. Maybe make it fixed at the top (or bottom).

That way after I've checked out the links, voted, etc, I won't have to scroll up to go to another alphabet, and then scroll back down. I'd imagine once you reach letter Z, a new user would find that flow a bit annoying.

Cool website though! I love Every Frame a Painting. That guy has awesome analysis on film!
