Is not it more important it works for your setup than have the coolest and newest framework running? Look at Gmail... it's internally really old, nevertheless very successful and good enough for the use case.
Agree. But when you are a startup, working on limited resources, you often worry whether you miss something, whether you are doing something the hard way etc. So it is not exactly 'sad about being not cool', but more like a worry on 'not using something that can apparently increase productivity'
