With one post you won’t get anywhere, you need to put some more effort. I have my own community, which is quite a bit more niche than yours, but by posting everyday it has been growing slowly.
Yours has lots of potential but needs more people to find it. Most people find a community from a post and people tend to look at newer posts, so you have to put something out regularly.

The linked study in the article has many of those, starting at page 20

Turns out forcing people to use Twitter less makes people use Twitter less, what a discovery!

On Reddit I just made a few comments and posts, mostly a lurker.
Here it’s completely different, I have my own magazine, where I put the effort of making a post daily, and it actually feels better than lurking.

I’m in the same situation, I’ve made m/rhythmgames with also 3 subscribers, no responses yet but still better than being on reddit!
