I am in the process of installing a new comment system on the blog. Do not be alarmed if there seem to be comments missing. They will return in a little while!

UPDATE:
I have installed the IntenseDebate comment system. There are some cool new features with this system, some of which will require opening an account with IntenseDebate.

• Commenters receive email alerts when a response to their comment is posted, linking them directly to the response.
• Respond to comments with ease via email.
• Option to send a simultaneous tweet when you post a comment.
• Comment voting.
• Comments can be sorted by date, rating or latest activity.
• You can embed video in your comment.

Give it a try and let me know what you think!
