Anybody who makes tech decisions based solely on what PR teams say is naive and incompetent at best.
only a year or two later, when teams that went all in on MongoDB at the behest of MongoDB's marketing department started realizing they'd been sold a bill of goods, did the slow and arduous march back to what continued to be the best generalized solution for 95% of data problems, the ACID compliant relational database, begin to occur. given that, this blog post seems really behind the times.
No, mongodb’s PR approach and results were largely uncommon at the time. They didn’t advertise directly but instead targeted and amplified dev communities - as detailed in the article linked earlier.
The result was that people not associated with mongodb talked about mongodb at various dev conferences and in blog posts. People didn’t want to listen to PR teams then too, but they followed their peers.
Testing out technology on important projects is reckless and is a risk a lot of people take but push away any responsibility for.
As a professional, before I suggest to use a technology at a project, at first at the very minimum I spend some time with it to learn the ins and outs. Every technology has cons. Just because you don't know them does not absolve you from responsibility for them.
The reality is that most applications are boringly similar once you define the problem in simple words. There is very rarely a need to use new technology. It is my experience that it is usually better to use technology that is not necessarily cutting edge but one that you know well and that you can easily hire people who know it well.
Because no technology is perfect, but it is much better to know the cons ahead of time and know you will have people who will know the problems and who can find reasonable solutions for.
I am personally sick and tired of people who first advocate for new technology to be added to the project, touting its supposed benefits, not knowing the cons, then don't want to take responsibility once we actually find the dead bodies.
As it is their "duty" to twist the truth in this way, it is our role as the users of these technologies to present things as they are.
