Title: We recently released a new version that uses constant urls for vote arrows and reply links on comments.  This should make "expired link" messages less common, because the supply of closure ids won't run out so fast.<p>The new code is gross, as I feared it would be.
In other applications you might be able to postpone this compromise.  The big problem for News.YC turned out to be crawlers.  They burn up closure ids as fast as real users, but the traffic you get from them is a function of the total size of your site.<p>We also made a few optimizations, so the site should be a bit faster.
