I think that instead of a list box at the bottom of the page, you have a slider on the side of the page that annotates the article with that users comments. That way specific arguments/comments can be made right in context with the article. Also this will allow for easier detection/elimination of spam because it won't annotate correctly (at least at first).
This would make reading the comments easier because they are in the context of article and reduce the amount of quoting of the original article.

This idiot is ... well an idiot.
The internet wasn't built in its current form!
It evolved into what we see today. The equipment used to build ARPA-net and such networks that became the internet was never supposed to be the high speed, huge subscriber numbers, massive number of application, porn-delivery system that we have today. It was made to exchange simple data. That was it.
And you can't just UPGRADE the internet (pssst... its not like in southpark and its just a big Linksys WRT54G router... really... honest!) Its a lot of moving parts.
I hate it when people with ZERO knowledge and less history try to say something is broken because their little app doesn't work correctly. Here's a hint... write cleaner, more efficient networking code!!! You'd be amazed how well that works (too bad this moron seems incapable of that).

Stupid should be painful!
