This all sounds very interesting, but what caught my eye as a casual observer was the following information on page 19 of the resulting paper.
Have any of you ever written anything similar on any of your papers? I wonder what similar piece of text might accompany a TCS paper. Will we ever see a TCS article stating anything like the following piece of text?
K.W.K., V.E.V., and B.V. performed experiments; N.B., T.A., D.D., A.T., and M.A.N. developed the mathematical model; and N.B., T.A., D.D., B.V., and M.A.N. wrote the paper.
X and Y proved Lemmas 1-4 and Theorem 2, Z proved Theorem 1, contributed ideas to the proof of Lemma 3 and found an error in the original proof of Theorem 1. Author W wrote the paper and was the main driving force in previous joint work that led to the development of this paper.
And what about papers that also report on implementations? I can't imagine how detailed the description of author contributions would have to be then.
I feel relieved to live in a research environment where we collaborate and mainly use alphabetical order amongst the authors---and not just because my surname is Aceto :-) I personally like to work by closely following the Hardy-Littlewood Rules for collaboration, whose spirit is very much at odds with the identification of author contributions.
