Actually, I'm not certain if I agree with this statement of your's here OldGreyWolf:
"Those posts that beg for criticism stand out clearly and anyone with any common sense can see them. I figure it is better to let them sink to the bottom of the pile uncommented than to keep digging them up to the top of the stack with negative feedback."
Rather, I believe some of this is rather confusing and complicated for first time want-to-be-cruisers, or even those with a little sailing experience under their belts and not always intuitively obvious for those with"common sense". Bringing out alternative argument allows for subjective review in the reader's mind. Letting this "Sinking to the bottom of the pile" may have a good ring to it for those who want to shrug off and avoid any sort of contentious dialogue, however, getting to the heart of an issue does require some discourse, negative or positive.
As I previously stated: "There are a number of reasons why I think a questionable reviews should be contradicted. Among others,---It might give someone sincerely interested in assessing a ship or cruise a misleading impression.----- Sometimes review points given a cruise or aspect thereof are tallied up to provide an average pier opinion assessment. Inaccurate negative ratings can skew a survey, likewise, so can overly positive ones."
Maybe I'm just from the old school and learned to provide some negative feedback even though it was not welcome: For instance:
"First they came for the Socialists, and I did not speak out—
Because I was not a Socialist.
Then they came for the Trade Unionists, and I did not speak out—
Because I was not a Trade Unionist.
Then they came for the Jews, and I did not speak out—
Because I was not a Jew.
Then they came for me—and there was no one left to speak for me."
