This is a request for the proper way to do things as a reviewer on code review. The question and answer can be found at Modularised Document Construction.
I just downvoted an answer that in the first line said it wasn't an answer but a comment and the comment field wasn't large enough. I didn't put a comment for the downvote, because I didn't know what to reason to quote, but I know code review really isn't a place for opinions. The poster is new to code review but has a decent reputation on stackoverflow.
I ask partially because I lost a reputation point, but mostly because I really wanted to comment and I couldn't think of what the proper response was. The answer seemed like a knowledgeable rant rather than anything else.
Should I have just left it alone, flagged it for moderation or ???
