Adding a Comment Section to my tutorials.

I have a lot of tutorials and articles in my app (link below) and I’ve been getting a lot of requests from users to implement a blog/reddit like comment section for the users to discuss.

Is there a library or some SDK that can help me with this?
Again, I want to have a separate comment section for each tutorial. It may require the users to login but preferably should work for “guests” too.
Free or Paid, any will do, but it should be good.

(As an example, the app iFunny too has a comment section for each funny picture, I’m trying to do something like that…)

You can see Disqus comment system but I am not sure if it will work out for your requirement. Just a wild guess.

Check out … I used it and its pretty easy to integrate

Could you possibly give me the link to your app?
I’d love to see it in action.

(I’ve tried several other apps too, just want to be aware of the popular features being used by devs…)
