I was answering this question but when I answered, my answer was converted to a comment. I think I understand the point of this system but I still feel robbed. The answer I posted was short but complete, had reference material and was correct (I hope or now I look foolish). Shouldn't I be allowed to receive credit for this answer or am in the wrong here?
If the linked answer, sufficiently answers the question, then the new question should be closed as a duplicate (in your case, flagged for closing).
Else, you need to include the explanation and relevant matter in your answer.
Answers should be self-sufficient, and should include any necessary content from external resources within them, with attribution.
I quote stackoverflow's How to Answer.
A link to a potential solution is always welcome, but please add context around the link so your fellow users will have some idea what it is and why it’s there . Always quote the most relevant part of an important link, in case the target site is unreachable or goes permanently offline.
You just posted the link as an answer with your assertion like "no, I don't think you HAVE to have it". You neither quoted the most relevant part of an important link nor added context. Answer is a statement of your known solution to given problem , whereas comments are giving opinions on a problem. If all needs to be done to answer a question is to post a link to an answer for a similar question , then the question should be flagged as duplicate.
