Note: This is a non-commercial site. I do not own any of the photographs but all are used with permission of the owners. All are hyperlinked back to their original sources, except for the Linus WriteTop, which is also used with permission of the owner. Visible copyright notices were maintained when part of the original images.
Hyperlinking to this document is welcome. Journalists, researchers, and students are welcome to quote from this document. Please do NOT reprint anything without crediting me -- that is plagiarism and stealing.
Rant: Seriously, we love links and reasonable quotes, but PLEASE ask before copying any big chunks of my work. Whether new media or old, major publication or random weblog, nobody has the right to wholesale republishing of content they don't own without permission. Arguing that "it's the new way" simply makes someone less credible. Be an ethical netizen and don't do it.
