For the amateurs like me, remember this is a personal opinion. If you haven't heard of this guy or familiar with his DB usecase (which I am not), you should be smart enough to know not get on the bandwagon.
People who are religious about stack either have been working with it for ages and testing it to its limits or are just writing SEO blogs. Flow my stupid plan if you want to really want to get preachy about DB. I started with CSV, then SQLite3 then I stopped. I am familiar with the syntax and basic workflow of MySQL and PostGreSQL just so I can get a job. I still use SQLite3 because it works for me period.
