Not sure what you mean by pretty serious about the web, infrastructure and platforms. To me this reads as an oxymoron because Python is not a pretty serious language. It's a toy at best. There is not a single feature that Python introduced or pioneered in the computing arena. It's a mismash of bad ideas from other similarly bad languages, wrapped in user-friendly paper. In that regard, it's very similar to Perl, but a lot more dangerous. Unlike Perl, there is nothing immediate in Python to warn you of the pit you're digging for yourself, especially if you're a newcomer to programming (as a substantial chunk of the Python community is). The troubles begin when you make the colossal mistake of trying to use Python for more than it can do, try to design and architect actual systems with it but I digress. On the other point you made, Google, Facebook, Twitter etc are using C++ too. Does that make C++ a good language for architecting substantial systems? Show me (1) system of substantial size implemented in C++ that hasn't turned out to be a DISASTER in anything _but_ performance. When your browser can be taken over a million ways to Sunday _just because_ it's implemented in C++, do you think Google, Facebook, Twitter etc give a damn if _you_ don't? Same argument for PHP and Facebook. Would you say that these companies are "pretty serious" about web, infrastructure and platforms? There are good languages out there, suited to architecting systems that are maintainable, secure and evolve gracefully. You won't find them simply by looking at what Google, Facebook and Twitter are using. You will need to try harder.
