I've noticed that embedding a comment form into a blog encourages readers to post comments, as opposed to providing them with a link to a comment form.

Blogger had historically provided a link to a blog comment form hosted on their server. But a few months ago they added the option to embed a comment form on your blog.

So I gave it a try on my beef jerky blog.

I found that this blog is now fetching about 1 comment per day, as opposed to 1 comment per week using the link.

So it seems people are more likely to comment if you reduce the number of required clicks.
