The Open Feedback Publishing System (OFPS) is an O'Reilly experiment that tries to bridge the gap between private manuscripts and public blogs. Following on the let-them-comment-on-everything model established by the Django Book, Real World Haskell, and Mercurial: The Definitive Guide (among others), OFPS allows readers to read in-progress O'Reilly manuscripts, communicate suggestions with the authors, follow others' comments, and directly participate in the development of new books.

Manuscripts developed with OFPS sites allow the authors to publish the in-progress work as whenever they think it's ready for public comment and then update the site with new versions as the text is improved. Authors note sections of the text that they'd like comments on (potentially down to an individual paragraph) and that allows readers on the site to comment on that particular section.

Custom software recreates various Sol LeWitt drawings. The software also posts instructions on Amazon.com’s Mechanical Turk. Human workers execute the drawings online based on the instructions from the program. The workers are paid 5¢ for each drawing. The software then assembles the drawings in a grid. The computer generated drawings, and the grids filled in by anonymous workers are displayed side by side.
