But you tap into more of the power and audience of Medium when you’re part of shared collections. To do this, simply submit your story after you’ve published it to one or more collections you think are relevant. (We now have collection search, so you can more easily find them.) You’ll be notified by email if the collection editor makes a decision on your story.
Writers are always asking me: "Do I REALLY need a website/ blog?"
It's up to you, of course.
If you're in this camp, and don't want your own space, Medium might be for you.
Although I haven't used Medium, I probably will. It's gorgeous.
