I agree with this one. I have a niche open source project (ntfy) that is somewhat popular in its space, and my promotion so far has been almost exclusively in the r/selfhosted subreddit. It is very very tricky to find a subreddit that will even accept self-promotion, though, and you will always walk the line.

My strategy has always been to be humble, be kind, respect the subreddit rules, and only promote if you have something actually valuable to share (new features, relevant things). And then only one per month or so.

And, as OC said, posts with screenshots or GIFs do so much better.

I'm a Ntfy user and I really love this tool! Thank you so much for your work

Corroborates my experience, that is what I did to successfully get some attention for Lusift (https://github.com/lusift/lusift).

That's very meta. Explaining how to promote open source software by promoting some open source software. I like it
