Showing scores up to flicky1991 on (page 207).
Updates are currently disabled because the xkcd forums are offline and I don't know if or when they'll be online again. You can still see the scores as of the most recent successful update, and graphs and looking at previous scores should still work. If the forums have come back online, it'll probably take me a couple days to get around to reenabling updates.
