If the first result is posting of a perfectly cogent comment, an intermediate result will be the rapid accretion of many comments, some of which may be equally cogent, but many of which will be trite, trivial, and feeble attempts to "jump aboard" the discussion.

The end result often will be bickering about everyone else's comments, unless the bickering is supplanted by outright hostile attacks.

So what's redundundant?
