I've updated the site to replace the Mango built in commenting system with Disqus. Since Disqus is well used, it seemed like it might be a more ideal mechanism versus dealing with moderation and having to deal with captchas and stuff of the old system. Hopefully it means more/easier commenting 🙂
I decided not to import the old comments, since there were not that many, but they are still available to read above the new Disqus ones.
