knowing that you are not knowledgeable enough about a topic in order to broadcast your opinion to the world as if you are an expert in it is a virtue
very easy to lose respect for someone when they jump into every topic as if they are an expert
in tech there's also this balance between sharing what you learn in public, and imposter syndrome
in this case being a good communicator, period, can give you a lot of credibility as you learn (and will help a lot of other people as well as you share the knowledge you're gaining)
