I know what you're talking about.
I don't know what to think about it though, ive seen sites that do it, like Mac Rumors. The comments button on their main page links to a topic in the forums.
In order to do this we would need a new forum dedicated to front page news. Most likely solution would be to make it a sub-forum of the SEGA Discussion forum.
I've learned a lot about altering wordpress over the past weekend, so I know something like this would be possible with enough cussing and pulling my hair out trying to figure things out. It would mean guests could no longer comment though, they'd have to register for a SEGAbits forum account.
Eh... something to think about
I'll talk about it with the other staff. Thanks for the feedback.
