In my opinion, there are two parts to why asking questions is awesome (and because of that, you become an awesome Hashnoder by asking questions):
What came first, the question or the answer? Right: No questions, no answers. So in order to help the platform become awesome itself, it is vital to have questions. The higher the quality of the question, the higher the quality of the answers. So try to ask good questions which spark a discussion. We are not StackExchange. We want to discuss, not solve (we have a discussion of the day, not a question). We are not only machines, we also want to put a social aspect to it. That's why Hashnode is the nicest and greatest community I know. You are awesome if you can be a part of it. Asking questions is a part of being a Hashnoder :)
Never stop learning. The question is: Why should you not ask questions? By asking questions, you can learn a lot about things you did not know or how others think about a certain topic. Asking questions will help you become more liberal, as you can see that there isn't always one answer to a question, but it depends on who you ask and what their arguments are. Very often, you do not even dream about what kind of things are important to others. Asking questions will broaden your mind!
