if you're running a business there are good reasons to choose tools that are reasonably well known and widely used, regardless of whether they're the absolute best available on the market. The biggest reason being that it's a lot easier to find developers who know or are interested in learning a popular tool than an obscure one. Recently, I've been questioning the exact value of using popular tools because it's easier to find developers (vs other reasons). So much of what a business is building and providing is bespoke. Even if you use a popular framework that makes your job posting buzzword compliant, that can end up being a relatively small portion of the knowledge required to actually be effective writing software for your business's industry. This goes doubly for organically created internal business processes, which are, nearly by definition, bespoke and won't be found in exact form anywhere else. Now, if you've got good, strong project managers who know your business's industry (rare, IME), then maybe the primary knowledge/experience the programmers need is only on specific frameworks. Obviously there's a lot of wiggle room here. Both early stage and established companies and code bases could make use of people who are either wide breadth or deep depth, there is no one guiding principle. Are you really going to turn down the candidate who knows 15 languages and frameworks but doesn't know the one you use? Or is this just your bias because you don't feel you'd be able to effectively interview them because you don't know as much as they do?
