I'm just asking myself if this belongs to hacker news. When does something deserve to be posted as "Show HN"? Does the link to what someone wants to show us lead to a rich discussion about tech, start-up, programming, business and other topics of general interest here? Is it a interesting website, that we can experience and talk about? Is it code? Is it an interesting business idea? In this case, I think this "Show HN" post is advertsing only.
