Yes. right after i posted it occured to me that you were probably referring to more front-end management. was a little to quick to fire back. i really love the efficiency at which blockchain.info parses the blockchian in real-time. if they were in fact using RoR for this, that would have been a HUGE +1 for the platform/framework.
wow! this IS an awesome site. i'll be adding this to my bookmarks. thanks.
