Hallo! So on other fora I see these lets play threads where somebody starts a (computer) game and take screen shots and comment on what happens during the play. People following the thread can ask questions and make suggestions. I thought this idea might work with articles as well. You choose an article and read while commenting on the ideas used in the article and rederive some of the calculations and so on, such that somebody from outside this perticular field can still follow the article. If the reader gets stuck she can ask questions to the audience as well of cause. Has this been done before( or is it happening as I speak?)? And do you think it might be a good idea?
