Yes, I am saying that. To be more specific: I saw the current Haskell
logo get put back in the top position even though I had pushed it down,
and I saw three of my choices which I ranked quite highly, pushed
down to the bottom. Scarily bad.

However, I am now hacking together a quick-and-dirty utility for
ranking things which I will put on hackage. I'm not sure that anyone
other than myself will use it, but it's fun hacking it up.
