I like the comments policy of the Blog Herald.

It’s a good idea and something I’ll probably be doing on my blogs as I continue to get spam, and otherwise irritating and distracting comments on posts.

If you blog for long in almost any field (unrelated to your dog or cat), you’ll find self-promoters who merely want to use your blog posts as free advertising for their services, or simply build traffic to their own blog.

You’ll have to make a plan for that … and think through the positive and negative benefits to allowing or dis-allowing such actions.
