I like 37 Signals and their general message, and certainly appreciate their willingness to take a strong, uncompromising public position in support of what they believe. That said, my biggest objection to their whole discursive space is that a lot of their advice is implicitly elevated, both by them and by those who listen to, interpret and relay the message, to a more cosmological status than it should be insofar as it's characterised as general "business" advice. It's not. There is very little in their general methodological core that is useful unless your business model is exactly theirs: selling subscription-based hosted web applications. Most of the same advice they give would be extremely ill-suited toward other domains of commercial endeavour within IT, never mind anything capital-intensive and/or outside of mass-market technology per se.
