For many (small) sites, having comments is a net good, but theres some sites out there that its like a plague. Think of it this way: I like to walk around the city. I do not like to walk on sidewalks that have piles of dog excrement and puddles of urine.<p>Can I walk around it? (of course)
Can I hold my nose? (sure)<p>But, wouldn't it be nicer if it <i>just wasnt there</i>? :)
