I'm sure it's indeed something like that. I think it also comes down to, at least partly, having a culture that is more about building components than systems.

I'm sure it's indeed something like that. I think it also comes down to, at least partly, having a culture that is more about building components than systems. I suspect it could also be the "buzz" factor. The press release about building a new system always seems more exciting than one about solving a familiar problem with boring old existing software.
