> Lacks reliable independent secondary sources to establish notability as required by WP:GNG. Every source is WP:PRIMARY. Every one of them. Googling turned up posts to online discussion forums but nothing useful. Additionally, I note that the decision to delete at the previous AfD was unanimous for the same reasons.
> Perhaps think of it this way: a language becomes notable when people who haven't been involved in its creation start writing about it. If/when this language gets to that point you'll have no problem creating an article. At the moment, though, there just hasn't been enough uptake to get the coverage we need for notability.
The problem is that most sources about Nim are by Araq or not reliable enough.
That doesn't mean a language is not itself notable.
Anyway, there's plenty about Nim that is not primary:

That doesn't mean that the best resources aren't on the Nimrod website itself. But penalising a language for having excellent primary resources would be a bit crazy in my opinion.
Basically Nim cannot ever become notable unless there are press releases about it or peer reviewed papers written on it. And without a company like Google garnering/writing press releases and none of the authors of Nim are at academic institutions... Well this is awkward.
