Ask HN: How to shed my apprehensions about self-promoting my startup?

I'm sometimes on an online forum when someone asks for a product recommendation. My (bootstrapped solo founder) product can solve their problem, but instead of plugging my product, I hesitate and do nothing about it. I pondered why I do this and came up with several reasons: 1. There are so many people liking an answer with a competitor's product on that thread, that I feel insignificant. 2. I think people will view me promoting my own product as inferior compared to others being recommended there. 3. My product has a fraction of the features of other products being recommended.

Could you give me a mental model or framing, different from the one I have, so I can think differently about self promotion on online forums? I would really like to put myself out there but my internal objections inhibit any action on my part.
