One article addresses the question above. His answer was that he uses RoR which has a large community and he is therefore easily replaceable. My question, for freelancers in general, and web developers in particular is this: How do you address this question?
In this particular case, you could argue that more people know PHP and Python than Ruby, so surely one should avoid Ruby as well. Managers like to think of their company as a factory, and from this perspective, it makes sense to build your factory from easily obtainable parts. But the factory mindset only works when you want to manufacture stuff, nobody who takes a minute to actually think will say that you can replace any programmer with any other, as long as they know the same programming language or framework. Anyway, here's something I found interesting in that respect: http://www.dachisgroup.com/2011/12/cant-get-no-satisfaction-why-service-comp...
