Can't Sleep? Read about Scaling Web Apps

If, you too, happened to have watched Knocked Up tonight and can't sleep (and no I haven't been reading the "baby books" but I probably should be), you might try reading this fairly vacuous article/discussion called Why most large-scale Web Sites are not written in Java but it lead me to High Scalability which actually pretty interesting and reminded me of the cool Joyeunt Prezo from RailsConf I ran into a while back.
