A new, Los Angeles startup, HotOutlines.com has debuted its service, which lets students and colleges and universities upload their class notes, outlines, and study guides, and sell them for a commission. The new startup--founded by Jonathan Roven and Ricky Yu--lets students browse for their school, and then download study guides other users might have made available for their classes. The startup said it will allow students who took a course in a prior year upload an outline in exchange for another outline, plus share in any revenue from downloads of that outline or those notes. Commissions range from 20% to 50%, depending on how many outlines a student uploads; the site currently features a small number of notes from Loyola Marymount University.
