Why comments should be normalized
1) I only comment on things that you have to register for on VERY rare occasion.
2) If I have to register, and I comment, I won't come back (unless you are Lifehacker, chances are, you aren't)
3)If you use disqus, I get an e-mail that says I got replied to. That is crucial to me coming back to your site.
4) Easier to spot/find trolls.
Do all of us a favor, and use Disqus or something similar, it's easy to integrate,
and it will help out your return rate on the chance that you write something that I want to comment on in the first place.
