My one suggestion is you make it so that it deletes a server after 1 day of 0% uptime. It would make the lists a lot tinder and less of the dead servers that don't even run anymore.
Since your post we have decreased the period of time before a server delete. And we might decrease it even more in the future.

Nice! Saw it for the first time today. Very smooth interface with lots of servers to keep me interested
