Main focus is experimental evaluation studies and/or evaluation methodology
The Workshop on Experimental Computer Science, held in 2007, was not a conventional "systems" conference in computer science. The focus was not so much on computer systems, as on the experimental approach of studying them.
Let's build an "Experimental Evaluation in Software and Systems Canon", a list of readings on experimental evaluation and "good science" that have influenced us and that have the potential to influence the researchers coming after us.
