If you like to find out more about the world of finance and learn it in a narrative story format, i like:
* liar's poker (where they covered the BSDs (big swinging dicks) at salomon brothers, of which Michael Bloomberg was one of the orig (i think it was five) BSDs)
* monkey business: about the adventures of 2 investment bankers at credit suisse first boston, including how they bullshit their way through the interviews to get in, and subsequently hire expensive escourts, have sex and live it up.
* bombardiers by po bronson: good insight into the world of junk bond trading (i think they made a movie out of it too).
* po bronson has to be among my favourite finance/tech writers. he also did "the first $20m is always the hardest" (about tech startups, with a company which closely resembles AMD), "what should i do with my life" (about the seach for personal meaning, and careers), "the nudist on the night shift" (a chronicle about the dotcom days).
i'd agree that some of the pop/pulpy stuff like kiyosaki, anthony robbins, dale carnegie are written in an entertaining manner, but a lot of them are very derivative... they were based or rehashed from other source books. if you can access or read those original books, the knowledge you'll get, will make you realize than many of these guys were just touching the tip of the iceberg.
for NLP/hypnosis stuff, you gotta look at richard bandler (father of NLP's) stuff, cos once you see it, you'll realize that tony robbins is just 'nlp lite"
LTCM and Google: LTCM was saying the black-scholes formula to successfully dominante a global market of which they were a major player.
in google's case, they are the perceived as the market maker in a market where they have the greatest mindshare now.
LTCM's products were not deemed to be a must have for fund managers, but in the case of doing PPC, you can do without adwords, but you would be missing a lot of traffic.
