I updated postcardX.net's look and feel today with a few minutes of spare time. Code is here. The changes were taken fairly well; our growth rate is reaching 100 new addresses per week with over 10,000 hits per week. I'm going to slide the new system in (a python/ocaml self-serving hybrid) when the population tops 1000. This same code will also run my entire web site, and a part has been integrated into the medical device control system I developed.
