It is really impossible to argument something based on the fact that people that are supposed to be very smart are doing it. There's been a strong undercurrent of posts which basically consist of ad hominem "non-SQL databases are only for idiots who can't figure out how to manage an RDBMS properly". Pointing out that there are people who very definitely are not idiots and who can manage an RDBMS quite effectively, but who feel non-SQL databases are still appropriate for their use cases is, so far as I'm concerned, an acceptable rebuttal to that.
