Over at the Lisp subreddit, nhs111throwaway asks if anyone actually got a job because they know Lisp. The problem with a question like that is that you’re going to get only anecdotal information as answers. Still, it’s interesting to read about people’s experiences.
If I had to guess before reading those answers, I would have said that there are very few Lisp jobs and knowing Lisp probably doesn’t help much except as an indication that you have broad based knowledge. It turns out, at least according to the answers to nhs111throwaway’s question, that my intuition is wrong. Several responders recounted how Lisp helped them get the job they wanted. Sometimes it was a Lisp job, other times it was a job using a different language but they were able to leverage Lisp as a tool in support of the other language.
If you’re a Lisper and would like to get a Lisp job, you might find comfort in the answers. It really does seem, as Paul Graham says, that Lisp is a secret weapon that no one talks about very much but that gives its practitioners a big leg up.
