I agree with just about every word in Tim Noah's argument to end the editorial page. Take the damn thing out back and shoot it, it's utterly useless. As a rhetorical form, editorials are dull, cautious, plodding, poorly-written, and choking on their own perceived authority. They rarely add anything to the paper, instead stealing space that could be used for riskier, more vibrant op-eds.
If Kinsley really wants to go interactive, having an editorial wiki isn't the way to do it. Opening the page up for reader submitted op-eds -- like letters to the editor, but longer and focused on issues of importance to the community -- would be a much better and more engaging move. The left side of the op-ed page, then, could be on local issues and by local authors and the right side can continue opining on matters of national and international import. It'd be much more interesting
