Hacker News has banned other URLs before, from what I know, largely based around the theme of "stories here are irrelevant/infactual/not hacker news." Valleywag was. TinyURL is. I think TechCrunch is similarly useless as a news source.
i dont really understand the point of a blanket ban on articles from a website. assuming the system isn't getting "played",aren't the articles that members deem interesting supposed rise to the top? So why a ban ? (if this discussion has already been had elsewhere,please point me to it)
that sounds critical, but it's not. i agree completely with his decision. if this site were run as a democracy, it would eventually devolve into uselessness, as has every other site before it.
