Comments sections are like answering machines – you get all excited when you come home to check, and then cry when there is a big fat zero. Conversely, you want to pull out your hair when some hog starts gabbing away and wasting valuable space and more importantly, YOUR TIME.
It all comes back to anonymity, by making you work a little more to contact me; I am greatly reducing the amount of jack-assery that usually floods comments sections. So if you are dying to comment on something, if you have a genuine question, hell even if you have a grievance, feel free to contact me at firstname.lastname@example.org. I will most likely respond in a somewhat timely manner - unless you are deemed frightening.
