Several top law reviews, among them the University of Chicago's, have teamed up to produce The Legal Workshop, which will publish truncated and accessible versions of their published articles. Alexander Volokh's short-form version of Choosing Interpretive Methods: A Positive Theory of Judges and Everyone Else is a good example of what they're trying to achieve.
The commentary -- by Larry Solum, Brian Leiter, Orin Kerr, and Nate Oman -- seems largely positive. I agree that the degree to which the site will make it more likely that the lay public will read legal scholarship is likely minimal, though it might have influence at the margin. But even professors can't read everything, and I do think that the site will make it easier for academics to keep abreast regarding new developments in their field and others.
