Ask HN: What are some of the top sites to advertise your SEO products?

It's been so long since I have quit the SEO game and focused on programming my baby (and SEO related SaaS) that I have lost touch with what sites are required to promote it.

The only sites (where you can target an active SEO crowd) that come to mind are blackhatworld.com and shoemoney.com, the latter of which stopped becoming an option almost 2 years ago.

So... where can I hawk my SEO wares?

FYI: Google does not allow me to advertise this certain SEO product, unfortunately.
