For what it's worth, I have been maintaining more of _why's code than anyone else over the last few years, and no, I didn't 'read a psychological/philosophical book,' I read lots of them. ;) This stuff is broadly applicable across all of technology, not just _why: I happen to believe that grokking Deleuze/de Landa is incredibly important for technologists, especially on the web.

That said, you are entitled to your opinion that "there's not that much to it," but I have too much evidence to believe that's the case. I just hinted at it here; when you need to summarize an entire school of thought _and_ share how to apply it, it can get a bit lengthy, and I wasn't in the mood for that, but did have many people asking me "what do you think about the possible return of _why."
