I get what you mean, Would it do well being more focused on it's own or in an already established site that isn't as focused.
Sorry, this is a horrible answer but I believe you could be equally successful with it but as much as I like making new sites, it honestly gets old; would you be able to devote the same time and love to that second site or would the articles/links themselves do better on your existing site? That's the question you should answer, where would the articles do better?
Look through some of the other current discussions here, there are a few arguments for and against new sites for not-so-exact content, you should get a bit more varied answers in an indirect way.
