We recently decided to replace the built-in commenting system that comes with WordPress on Gizmos for Geeks due to its limitations and that we were spending too much time dealing with spam comments. We looked at the 4 most popular/capable comment replacement systems available now: IntenseDebate, Disqus, Backtype and JS-Kit’s ECHO. We briefly considered Facebook Connect, but since at least ID already supports FBC, we didn’t bother with it.

We ended up picking IntenseDebate, which by the way is made by the same company (Automattic) that produces WordPress. We won’t go into all the reasons why we picked ID, because your reasons will end up being different from ours and it’ll be worth the time to research them properly and understand what they can do.

Instead, here are some useful references that we used to help us decide. Good luck.

  1. IntenseDebate vs Disqus
  2. Intense Debate vs Disqus: Why I Nearly Switched
  3. BackType’s Co-opetition with Disqus, IntenseDebate

And if those aren’t enough to help you decide, then you can hit up Google to find additional discussions. How apt.
