Ask HN: How do you promote your product outside of Reddit, HN, PH, and IH?

Agreed. But this can be tough if you don't already have an existing following. I was thinking of including something like a "Change log" on my site where when I launch a feature, the user gets a pop-up that says something like "Here's all the things that we launched while you were away".

That's a good idea. I've considered that but my game is more similar to Wordle where it's a daily word game. It doesn't really fit in with the other games that streamers typically play. But if the goal is to simply get the word out, promoting it on a few streams might be the way to do it.

Do you feel like doing the content is worth the ROI? I would basically be starting from zero and from what I've heard, it's a lot of effort to go from 0 -> 1.
