I'm not sure what to say about the belief some people have that 'we need releases twice a month' for a stable, high-performance product. I don't want or need product releases twice a month unless there's a good reason.
I feel like the regular releases crowd is mostly cargo cult driven by a desire to emulate the big web companies who are constantly - and often infuriatingly - tweaking their products for whatever reason.
From what I can see, this desire/need for constant tweaks arises mostly because web companies tend to ship very buggy products, and because there seems to be this belief that a company is going out of business if their web page that doesn't change often enough.
