Scaling (why jango sucks)

Lots of babble, but this is what seems interesting:

- normalization is good, denormalization sometimes makes queries
  faster.  automate the denorm (cached db views?)

- sessions: stick it in a cookie (you really don't want to keep track
  of user state for big apps)

- "SELECT *" is fast

- JOIN doesn't scale
