1. Keep comments to 300 words or less. I know it is hard to be concise but try. All comments over 300 will be deleted no exceptions.
2. No promoting your own site. You can link to an article on your site only if it is pertinent to the discussion in the comments. Comments posted with the intent of promoting your site will be deleted.
3. No flattery. Saying things like 'nice post' is ok, and I appreciate the encouragement, but anything beyond that is unnecessary.
4. I promise to never delete a comment because of a dissenting viewpoint so long as it is presented tactfully. Obvious breeches of etiquette will be deleted.
