Myth: I don't want to comment because I don't want to intrude.
Are there bloggers out there who don't enjoy comments from random people they don't know?
I'm sure they exist but they have to be in the minority. As far as I can tell, comments are tokens of sweet blog love. Comments tell writers that someone is listening, that their audience isn't in their imagination, that people care.
You, dear readers, are great commenters. Thank you for the reinforcement.
