"Making simple software and charging heaps because we are hip and edgy..." Every time I see things such as these I think: 20-something, doesn't understand money ($20/month seems "too much"), doesn't understand business, not much sense of humor either, mostly pissed about other being succesful... The kind of people who write M$ with a dollar sign.
Based on the date the link was submitted to reddit was done around the same time as the Curebit fiasco. I like 37Signals but admittedly they did behave like arrogant aholes during it. Not something I'd expect from such well respected members of the tech community. The bit where DHH tweets their investors is what does it for me.
