If you regularly read our posts, you may have noticed our changes in the comment system — otherwise, you won’t see a difference.

You can comment as a guest, but if you get involved in an active discussion on a post, it becomes beneficial to sign up — you can create a personal profile, use an avatar (image), get access to the real-time discussion, share images, and even share your comments on linked Facebook and/or Twitter accounts. Not at your computer? Download the Disqus app for Android, and keep up with the discussion. Have an iPhone? That app is currently in development — check back here to find out more: http://disqus.com/mobile/#.
