Evaluating the alternatives is smart of course. I just don't understand why type-checking and speed were factors in choosing the language you were after. If they were, then why even bother looking at Python at all? It isn't a fast language and doesn't have type-checking. The rest of the article is spent telling me why these features aren't important. Both C# and Java have type-checking (though C# perhaps is a little more loose) and are pretty fast. Yet the article claims that Python is fast enough and that type-checking isn't a requirement because you're more concerned with value assertions (and unit-tests are good enough to validate them). So essentially the article sets up false premises and knocks them down one by one. Type-checking wasn't actually a requirement. Neither was speed. The only reason we are left with for why Quora chose Python was because that's what most people were familiar with. I'm not saying it's a bad choice or that your conclusions were incorrect. I just don't think it was a good article.
