I am a native AmE speaker, and have been wondering if my answers are on-topic here.
This thread brought up a good point, but didn't quite address my question. I am wondering if it is appropriate to answer from experience rather than grammatical knowledge.
I have been, and my answers are getting accepted, but is this what's intended in ELL? Occasionally, a commenter will point out that there is no dictionary definition for the usage I'm describing, even though it is used colloquially. I feel like this is part of "learning English," learning the usage as well as the definitions. But is it dangerous to answer questions with unofficial English? Could this be irresponsibly teaching to bend/break rules?
