A comment like "duh" is always cool gives me the impression that you have looked a little at my blog or at least that entry
a comment like "whatever" is great it means I need to explain things a little more.
a comment such as "get a real life and stop wasting my time" means you probably don't care cause it makes no difference to you what I type
when a comment saying that my blog "is not good" in one word or less occurs I will look to examine the commenter's blog.
when a friend or someone I know comments on my blog then I try to reply
if there is a comment from outside the touch of two circles then the reply will be conscience of the comments meaning and form and details behind such said comment
