I'm not familiar with the rules of this site. I'm rather active in other SE-sites. This question was closed and the given reason was that the OP was asking for learning resources. Lots of questions in the beginning of the site scored high: they were the canonical questions everybody poses. But now, a question with +9 votes is rather an exception. If the respective answer scored +12, it means that it's very useful. It is suspicious to me, that after half a year a question with those characteristics was closed.
Why was it actually closed?
First, it is not a learning resource.
Isn't asking for an alternative to a dictionary which every native speaker knows and uses, but whose interface doesn't work, allowed?
Why is asking for resources forbidden? In case it is there are always evolving rules. When a new site appears, we do not know everything and therefore we cannot deduce the most perfect rules and letting them be totally fixed doesn't work: that's why the meta does exist, I guess.
If those rules of closing questions do apply, why was this question closed 6 months later?
