ApertureExpert.com: ebooks and advice for users of Apple's pro photo management app

Pro photog Joseph Linaschke, whom I first met back when he was part of the official Aperture team, has launched a new site for users of the popular Apple photo management app (it's what I use to manage my photos). ApertureExpert.com offers free "tips and tricks," and he's selling instructional e-books. BoingBoing readers get a 25% discount on those for a limited time. Use code "BB25" on checkout.
