I love reading about how companies use various technologies and how it works for them but I am personally weary of dealing with people who bring up these writeups in language wars without qualification–I'm sure you know the usual "Google uses it, so it must be good" or "Facebook stopped using it, so it must be bad" kind of proposition. Actually, I've written many words on the topic, many more than I have put there; perhaps you've seen it already ;)

But to be clear: I'm saying that reading about other people's experiences with a language (including yours here) is useful in making your own decisions, but you must also account for how you and your usecase are different than the one that was presented.
