Online commenting debate

The New London Day has two really interesting opinion pieces on online commenting (see here and here). If you get a chance to read them, please do. Given that this is a hobby for me, I'm wondering if there's any technology out there that could both maintain the realtime nature of blogging, but also block the anonymous comments that do little besides demean people.
