Very much this. The comparison he tried to draw with Linux distros, same deal. Who cares? Try one. You're a hacker, go grab a language and hack some code. No, you won't be as good with Python when you start as you may currently be with PHP, big deal. A weekend project is the PERFECT time to learn a new language/framework. Sure the weekend may become 2-6 weekends, who cares? If I am not mistaken, Twitter and Reddit have both changed very large parts of their codebase from one language to another, so I don't really know if I buy that argument either. Finally, I think programming languages should work for the guy writing the program. I made a point of learning everything I could (and continue to do so) about every language I come across. So when I need to do something, I have 6-7 toolboxes at my disposal, as opposed to 1 or 2. I write in 5-6 different languages every day at my current job, and have become a very valuable employee because of this. This is coming from someone who has only the most basic experience with PHP, take it with a grain of salt.
