Well, giving DISQUS another go.
Use the comments as before, none where lost in the migration (thankfully). You can vote up/down particular comments that you think are deserving (or not).
You can still post as anonymous by checking the "I'd rather post as guest". It will need an email address but it doesn't check to see if it's valid. Better still login using one of the services like Twitter, Facebook or G+.
Another feature! At the top of the comments section (when you've clicked into the post) you'll see a [Star] click on this if you like the post! It's more than likely the "Reactions" voting will be removed soon.
Drop me a note if you're having problems or post a comment to this post!!
