First posts go into a queue for review and feedback - since sometimes people react badly to feedback, such feedback is anonymous.
Now that the duking is done - and why its community that the comment is attributed to...
Lets get down to some actually useful feedback.
While I guess the 'skeleton' of the answer is there and arguably it is self contained - it looks like relies heavily on an external source.
I'd guess the reviewer felt so, and its a little unfair to blame poor ol community. You might hurt her feelings .
While copying over the entire post from the external source is plagiarism, a little more detail organic to your answer wouldn't hurt. In this specific case its worth taking the advice in the spirit its given rather than take it a little too personally.
