These aren't letters. They're comments.  Readers should give them the weight they're due.  More comments are better than less, even if they're a bit offensive.  There should be boundaries governed by outright libel and abuse.  But comments often are a lot more interesting and funny than the articles.  Once real identities go on them, they become politically correct.  And some commenters won't be able to contribute due to their sensitive work or family situation.  

ADN seems to be closer to striking the right balance with this commenting system. Not perfect, but better.  I do miss the ability to block out some commenters who are repetitious trolls who only get their kicks out of provoking rather than enlightening.
