Comments:

Allow comments unless your blog topic is really controversial and you’re likely to get a lot of flaming (people lashing out at you for what you have to say). Allowing comments is good because it gives more food to the search engines and keeps your blog updating and fresh even when you’re not posting to it.I usually let anyone comment, and don’t limit it.Don’t show the comments in a pop-up window, because that will prevent the crawlers from being able to get to the content since it’s javascript-based.If you’re concerned that people might flame you, but you want to allow comments, enable comment moderation so that you have to approve each comment that is added before it goes live.If you want to be notified when a comment is made, set the Comment Notification Address to your email address.
