Ah that makes sense. When I read blog my mind goes immediately to personal blogs which to me it means a space where you write about everything that interests you, not some some specific topic. But you're right, if one doesn't care about that they can achieve the same with some more specific and more focused platform (for example GitHub as you mentioned)
