Are Commenters Good or Bad?

An interesting controversy exists concerning allowing comments on blogs. Recently, Michelle Malkin finally updated her blog and made the decision to allow comments. Some people like this person think that only losers post comments to blogs, but I think the ability to leave comments is a positive feature of the online media.  I enjoy leaving comments and I enjoy receiving comments.  The only downside is the enormous volume of comment spam and the high percentage of unacceptable content left in the comments.  Kudos to Malkin for enhancing her blog. I think it only makes her great blog even greater.
