An anonymous Microsoftie is running the contents of internal MS emails on his blog. Bad form and a serious breach of email etiquette (Never mind company policy) but it's published and now can't be unpublished.
The contents of his post does give a nice look at life as a Googlebot. I'd like to believe that the management layer wasn't that flat for a company of Google's size but it makes sense when you consider how singular their market focus is and reminds me a lot of the Meta-programming model (As developed by Charles Simonyi) Microsoft had in place during it's early days. That didn't last for too long as Microsoft grew and Google's system probably won't last for much longer either should they begin to grow beyond their core market of selling ads.
