I rather enjoy the comments on the blogs I read. Especially my own where often someone will bring up a correction, addition, etc and just in general add value to the post.
Comments can take up significant vertical space. I hate going to a blog post and having no idea how long it is because there are pages of comments below it.
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.
Can I walk around it? (of course)
Can I hold my nose? (sure)
But, wouldn't it be nicer if it just wasnt there? :)
