I'm aware that the comment protocols on this platform (Blogger) are awkward, and discourage participation. I've provisionally opened up comments for anyone. I'll see how that works out while I look into other comment systems. I'm considering DIsqus, Intense Debate, and Livefyre. If you have any experience with, or thoughts on, these comment systems, please share them with me -- in a comment, or by email (contact form on right of page).
