We could get into a semantic argument about what "lots" means. But open source is very much a corporate thing now, and lots of dev companies do indeed have an agile-inspired workflow at least.

Re: that fun thing, yes, but most projects aren't fun on a daily basis.

In any case, what I originally meant was that agile is not perfect, but if you've seen startups who don't know any development workflow (ie neither agile nor cascade), software dev grinds to a halt really quickly as they try to reinvent an entire field of management.
