Is self promotion allowed here?

HN is a great site to attempt to gain exposure and new subscribers.

I understand why someone would choose to post their content here, despite my other comments railing against self-promoters.

If you make it to the front page you will gain a great SEO boost simply due to the new links that pop up on dozens of HN copy-cats that exist elsewhere[0]

So, I say go for it if you have content that you want to share!

I think so yes, and if you are building something cool, then you can use Show HN so it goes under the 'show' category.
