The two worlds are diverging rapidly. Traditional enterprise software development (the kind associated with “programming in the large”) tends to be slow, costly, inflexible. Solution sales, marketing, and support tend to be correspondingly process-heavy and inertia-laden. The Web, on the other hand, is agile, fun, and friction-free. It has changed the way people look at computing. It has changed expectations (and conversations) around marketing, pricing, maintenance, support, and just about every other aspect of the enterprise-software experience.
