Via David Chalmers, two sites that you might be interested in following, and that I shall be tracking via the philosophy papers blog.

First, the philosophy page at thematrix.com currently includes papers by Dave Chalmers, Jim Pryor, Richard Hanley, Colin McGinn, Julian Driver and several other philosophers.

Secondly, the NYU seminar on Factually Questionable Discourse has plenty of links to papers on, well, factually defective discourse.
