Disqus, comments system has released some new user-centric dashboard features for all commenters:
If you're already logged into Disqus, check it out by heading to disqus.com/dashboard:
Follow people that interest you on Disqus. After you choose to follow someone, his or her activity will show up in your dashboard activity stream. (Use the "Context" button to get the full conversation!). Following people on Disqus means that you're subscribed to their conversations and recommendations as they read and discuss topics online.
To follow someone, just bring up their profile (click on their picture) and click Follow button. Disqus will also suggest to you people you may want to follow, based on your existing friends on Twitter (Facebook support is coming soon). You can find this on the left side of the dashboard.
The new activity stream will show you how many likes you've received on your comments, and who liked them.
