NEVER read the comments.

Matt Inman at The Oatmeal writes about the troublesome nature of comments for a content-provider.

While I can't really comment much on how all these comments would affect my production, I can tell you that they really affect my pleasure in consuming online content. Inman nailed it here:

You know why newspapers and YouTube and other content hosting sites enable contents? Because it increases hits. MaryBeth471 writes about an Enya video: "It's so peaceful." Then Sk8terH8R comes on after her and responds to her comment: "Enya sux like a Dyson with a collapsed star inside! Slayer 4evR!!1!"  Then when ol' MaryBeth checks in again, she gets a little note that she has a response to her comment. She checks back in, and discovers to her dismay that her favorite soporific Irish Ambian Popstar has been maligned, and by someone who loves devil music, no less! This issue MUST be rectified! And she defends Enya. And comes back later to see if Sk8terH8R responded. And, because she did, our troll will come back. This is a big source of hits on YouTube and your favorite online news sites. Remember-- they don't care if it's a chimpanzee checking in daily; all they care about is making that hit meter roll over again and again.

This does nothing for your pure enjoyment of the thing. It will NOT show up your online opponent. He's a troll, delighted to get a rise out of anyone.

The most likely outcome for you is distress. Say NO to irritainment.
