After a drought, I seem to have stumbled into a high-blogging period.
One of the things people use as a reason not to use Smalltalk is that they "can't find developers". I find it odd that we can simultaneously have developers who can't find Smalltalk jobs and Smalltalk jobs that can't find developers, but even leaving this aside, I've never seen this as a huge issue. My point of view is that the hard skill is programming, and if someone is actually a good programmer they can pick up Smalltalk fairly easily. People talk about these very long learning curves, but my experience from projects I've been on is that good people can pick things up much faster than you'd expect.
Bob Lewis of InfoWorld agrees with me here. The relevant quote is right at the end...
Which is the same thing I tell hiring managers who insist on experience with a specific programming language: A competent programmer can learn a new language quickly. An incompetent programmer who knows a language will remain incompetent forever.
