First, I never said "don't use SQL, even where it makes sense." The original commenter wrote, "advice to anyone deciding on a database". I strongly disagree with the notion that any practicing or aspiring creator should refuse to learn about and consider the full range of tools at their disposal, simply because there's a popular default choice. Specialized tools provide a form of leverage to those who understand and employ them wisely. Every problem I have ever come across that is sufficiently difficult and interesting to warrant forming a startup requires deeper insight on a technical level than "just ignore everything else and use X". Can you imagine if the founders of Google took this kind of advice?
