Curious about others' contributions, such as Vaswani, Parmar, Jones and Gomez, to the paper. What sucks about co-authorship in research papers is that you don't get a clean breakdown of who contributed what to the research paper, and the distribution (in more cases than not) is very much like a pareto distribution.
I'm talking from plenty of group project experience here.

Why? If you read a research paper for its content this is not especially important.
This thread is more about the people of course, and here we care, but that's not the point of a research paper.
