I've no idea if TFA is good or not, but it is very new and has only 4 upvotes.
The HN front page is a mix of new and popular-despite-age. So it's not surprising to find some barely-vetted things on the front page. (AFAIK the idea is that we're all suppoed to vet them, and the survivors stay on the front page for longer)
