I don't know which is the older, Hacker News or that Designer News forum, but I think the similarity is striking:

Both sites are on a company domain, added a "news" subdomain, and named the forum "XYZ News", where XYZ is a description of their audience, a positive one, to appeal to industry members.

I hope Hacker News was first, because if not, they will start harass this board over the naming thingie...
