@Jesse Friedman - After commenting, what do you think?

@Brandon Mullins - This is the way I do it. Of course, you can simply use Disqus or IntenseDebate to do the same things. In fact, IntenseDebate has their own plugin architecture so you can go above and beyond my commenting system.

@Anne - I think it's the easiest way to say 'Hey, I'm talking to you' in a sea of noise. That code is in my functions.php file but it's coded in such a way that it's specific to my child theme based on the Hybrid framework. Messing around with the code, I'm sure you could figure out a way to lift the Javascript bits for your own site.

@Octavian - Not sure what you mean by Tweeter but in a sense, you get threaded comments, just not as visually as you're used to.

@Daniel - On my site, I've chosen not to use threaded comments because that would introduce a second Reply link. The custom one I have and the one WordPress has by default. I liked the functionality of my link better. Although you won't see the conversation threaded normally, the conversation still maintains threads thanks to the Comment ID link added to the beginning of replies so everyone knows which comment is being responded to.

@Aldo - I haven't used that plugin and was not aware of it but upon browsing around, are all those options only available to the administrator and not to everyone? That makes a big difference.
