Given the title of this HN post, you should really be linking to your blog post, not the product itself. I clicked around your site a bit searching for your "learning to code" story to no avail.
However, I don't begrudge the OP, as he's certainly gaining lots of useful feedback for his site.
I just can't help but feel slightly gamed ;)
I also think that the blog post would have been much more pertinent to the OP's experiences and conducive to good feedback. Conceivably he chose the title because he wanted feedback on his experiences while learning to code, yet he got feedback about the product in general. If he was looking for advice about the site in general, a Show HN would have been more appropriate.
