I just significantly improved caching to further reduce the necessity of hitting Hacker News. This should fix a lot of performance issues as well as blank pages.
As for duplicates, I have tried to make that much less likely by putting the status closer to the update query. There are lot of hits per second, which causes that. (Queries take around 0.005s to perform; if 2 hits within that time period, then it could update the cache twice (or more)).
