Just a short update on the new commenting system from Disqus. Blogger commenting system unfortunately does not allow people to reply to a specific comment. I am testing the new commenting system to see if it will better facilitate discussion. All older posts will retain the Blogger commenting system, as I cannot upgrade the commenting on older posts without losing all comments. Would be good to hear feedback on this new add-on. You do not need to register with Disqus to comment and I will not be blocking / moderating unverified comments, as I have not seen much spam messages on my blog so far. Cheers.
