How to improve your blog commenting system?

Question

Blogs

There is a blog. The task is to create a simple and improved commenting system.
Your own . Screw something sideways - will not work.
That is, if we take the comment system itself, it will be a) without authentication b) name, email, website, comment itself.
I posted a comment, you can even with the left soap and a name, it was approved. All. Doing this is not a problem.
Can this be improved somehow? Simplify, perhaps. Or maybe something to add.
And that there was no tension for users. Normal registration-authentication is definitely not suitable. Perhaps only through openAuth - login through twitters there are all sorts, facebooks.
What else is possible?

Answer 1

The name and the comment itself should suffice.
You can also do a preview.
