"Perhaps it will be a site focused on Nodejs news"

They could call it "Hacker News".... ;)

Sure you could, but the point is rather to require this specific language. No option is totally without controversy, but this choice ensures a very specific audience (not just programmers/technical people, but ones who are into node) and anyone outside the audience is implicitly not welcome at all.

hmmm maybe you can make SEVERAL of these sites each in a specific tech so each person can get into their niche of interest

or different implementations all linked to the same DB ?

Although it seems a bit of a waste of time.

Hell no. This with metrics can be the end for all "X doesn't scale" or "X is easier than Y". With real code.

And call it "reddit" ! :)
