What is the business model for Hashnode? Who are you are you up against in the industry? StackOverflow? Others?

Your Interactor model demands dependencies directed towards the business logic and never from BL outward. DDD also has similar design ideas (Port and Adapters, too). Why haven't you jumped neck deep into Domain Driven Design? I have seen you say positive things about DDD, but you don't come across publicly as an advocate. Is there something with DDD that you find incongruous with your architecture/style?
