I'm pretty sure this is #1 on the frontpage because they gamed HN. I don't how it's different from all those themes. Except for the price and the landing page.
Dont' know if they gamed it or not, but I submitted same url without the crappy end a few hours ago before this one. HN is not able to detect doubled URLs?
yes, they "gamed HN" by having an affiliate program ;-)
