Ask HN: Do you promote your hobby projects? Why?

Why do you do it and why should anyone do it? How would you approach it?

Personally, I have a hobby project dealing with some programming issues I experience.

I simply want it to generate more debate around those issues and hopefully get some serious feedback regarding it ('have you tried X instead?' is not a very good feedback when every comment is like that, imo). However, it is proving to be a much harder quest than anticipated. It feels hard to do so without spamming.

So, what do you think about these topics? Thanks!
