The slowness is causing lots of duplicate questions and comments, as particularly with a comment you forget whether you pressed the button or not, click it again, and 30s later you get two identical comments.
Jeremy and co have done such a great job with their fork of OSQA... email notifications, code blocks, and so on and so on, it's a shame that using it drives you to distraction nowadays. Seems like the community is thinning out too... lots of once-only users, very little voting and commenting.
Personally, I'm off until performance and searching are fixed. (Except for the rare questions specifically about my plugins). Adios!
