I love design and features of hashnode as software because it is more than Q&A. I would say, HAAS, Hashnode as service to server community in different type of people. As StackExchange already have community for photography, math, travel, writing.
To Founders, Have you ever thought about it? also it can be Paid Forum Framework for revenues.

I think what makes Hashnode special and awesome is that it focuses on essentially one thing and it does that one thing right. Hashnode's platform is designed towards people who take interest in technology and software. This makes Hashnode communities awesome and pleasant.
There is a possibility in the far future that the Hashnode platform can be made into a "communities platform" but for now I think the main focus is on technology and software which is totally fine by me.
