Do you think you can make better success with hosted blogs like Medium ? I see a lot of articles by main stream products and services posted on Medium. It has become more like a Facebook page which people can follow. Even though it is a blog, it is has become a platform with participation like Facebook. ie, you can reach more people through Medium if you plan it well.
Looks like if you are an expert or a service / product owner, Medium is one good way to replace press releases.
