We just pushed live some search relevance enhancements so you should see more applicable results for your searches. There was also a bug with “Show next 25 results” sometimes not showing 25 additional results and we’ve pushed live a fix for that.
Recently we released some minor performance tweaks for the bug.gd Firefox extension. If you don’t have it already, pick it up on Mozilla’s addon site.
Beyond these fixes, our team has been working hard on a major site redesign. Stay tuned for some (hopefully) impressive changes in the near future.
