One of those was a day job where they understood the politics well enough to work around institutional bias against non-Blub languages. Later it was their own company where they could make technical decisions without having to justify them to non-technical people.
Bear in mind that the article was written by a product evangelist for a Smalltalk vendor. It's not surprising it has the perspective of assuming the tool and looking for the application.
Indeed. From the post,
"They have two good Smalltalkers with a couple of laptops. They use available WiFi and open source code, and they deploy on cheap, hosted Linux boxes. [ed. I'll interject at this point - you could use commercial software all the way down, like Cincom Smalltalk, and not pay a dime until large amounts of revenue arrives]."
and then pay a percentage of your annual revenue forever (http://www.cincomsmalltalk.com/userblogs/cincom/blogView?con...). I believe Franz Lisp works on this model as well.
