I think the key thing is to keep iterating and experimenting. Keep posting into the void, but don't keep doing it the same way every time. If your tweets get 5 views, don't just keep tweeting. Try a different platform, or target the tweet at a community/niche, or try presenting the post/content in a different way, etc. If you find something that works even marginally better, double down on that.

Often the people who seem to suddenly "make it" are doing this, but it gets left out of the story.
