I am program chair of Onward! 2012. What do you want to see?
Here is one thing I am thinking about. I understand that in the real sciences, conferences often accept papers based solely on an abstract. That wouldn’t work for Onward, or even most of CS. Perhaps we should instead use the opposite of an abstract: a “concrete”. That is, an example. A common problem with big-idea papers is the lack of examples, making them quite difficult to understand. Perhaps we ought to require authors to submit an example up front in lieu of an abstract. That procedure might be beneficial both for the authors and the reviewers.
