I’m following a few people (Matt Gemmel, and Marco Arment) in this, but I’ve decided to turn off comments in this blog.
My most popular blog post (a code snippet on how to fit all markers on a Google Map) largely is the only place that gets a response with the occasional comment. However, they’re usually “thanks for the help”, which I really do appreciate but I don’t feel that was the point of the blog post. Otherwise, it’s people asking for further support which I just can’t give over the comments of a blog post (mostly because people don’t check back).
Pingbacks – letting a blog know you’ve mentioned it in a post on your blog (WordPress does this by default) – seems the most sensible way to have a conversation online. It forces well thought out comments rather than spur of the moment outbursts.
