If you have to read another blog, at least don't waste time commenting on it. I
know people say that it doesn't take long to leave a comment, but it does. First of
all, if you know you're going to leave a comment, you have to slow down and
read the post carefully to make sure you understand it well. Then you have to
read all the other comments to make sure you don't repeat anything. Then you
have to think of something interesting to say that hasn't already been said. Then
you have to check back later to see if anyone replied to it. And for what? A
chance that someone might click through? You need to comment on as few blogs
as possible.
