That's true in general, but the business of tech can sometimes benefit from local knowledge. A submission about the best lawyers for tech startups in Singapore wouldn't really be appropriate for HN since it wouldn't benefit a large part of the audience. It also helps to have a site where there's a high chance that the person you're talking to is close enough to meet up for coffee. =)
