Looks sick
I’m looking through it but I’m confused one one thing.
Is it something that replaces your wp comment system? And if so, does it means when people can login with their twitter or facebook account then they dont create a profile on ur site but they r doing it externally?
i dont get it totally how it works or what it idoes
If you have an account on disqus.com you can easily track all your comments and the good thing is that when someone likes your comments you’ll received some points but I don’t know where to use it. I started using this tool last May I think when I read one mashable article and when I leave a comment it let me create an account in disqus.com. That’s how I met this tool. 
I think you can log in using your twitter or facebook account if you post a comment as a guess. not so sure though.
