I was working in a company where we built a new backend system and had the opportunity to chose the technologies we'd use. I was constantly looking at rethinkdb waiting for them to tell me "Yes, you can use this now," however their blog posts and announcements constantly had the underlying message of being in some kind of alpha or beta state. Admittedly, that was a few years back, so that could have been true then, but the feeling stuck with me and I just stopped taking it seriously. The problem is that they got a lot of attention early on and expectations were huge and instead of building some hype around it, they were actually too honest. In hindsight I, as an engineer, would have probably done the same, so I think there are some valuable lessons there about marketing and human psychology. At least that part the people at MongoDB did brilliantly.
