i think its good example of not "good enough" formalization. Afaik Orkut had a lot of operational freedom to do what he wanted with Orkut. it just nobody (the whole pool being semi-dead friendster at that point) had the answers what is actually important to build a socnet. Today we have 20/20 hindsight its absolutely terrible to have runaway adoption in 3rd world country that doesn't speak english... yet thats one of the axioms we learned "the hard way". And obviously that increased formalization (whats working, whats not) was helping Mark a lot when doing next iteration.
