They all include somewhat useful articles, but some of them (once you arrive) are also quite self promoting. I think the odds are quite slim that this many others randomly stumbled across articles on obscure domains and submitted them repeatedly, so yes I think the owners of them are in many cases responsible for them having been submitted to HN. But I wasn’t actually disparaging any of them, or suggesting anything inappropriate has happened. I guess I’m just surprised that HN as a community, with such a high degree of anti-commercialism on the site, has given these sites this much exposure.
