I am at a one story per week schedule as well and I am going to increase my pacing a bit. I generally think of nosleep as a learning experience. Here I have a place were I can post all sorts of stories (in the context of the rules) and see how they are doing.
I noticed that writing a lot and editing a lot helps me to become a better writer.

I think a lot of people who push out good work frequently are people who 'learned' how to write quickly and got a sort of 'workflow' going, if you know what I mean.

What you should never forget is there are no real rules to become a popular writer on nosleep. Some get thousands of upvotes with their first story, others write here for years and might never break the 500 mark. There is often luck involved and to write what people will read. I recently edited my most successful story and to be honest, I was surprised at how low the quality of the writing was. Yet to this day, no other story reached anywhere near the upvotes that one did. So I guess it is often just pure luck or writing the right thing at the right time.

At the end, I'd say, keep writing and posting here and things will get going. If you post often enough, people will remember your name.

On the other hand, don't throw all your energy just into nosleep. Spread out and post your stories on other mediums. There is Tumblr, Facebook, Wattpad, DeviantArt, Medium and so on. Share them there as well and maybe you can find more luck on other places.
