I had seen those graphs, but since some of the graphs include other details not supplied by the nominations I hadn't really considered expanding my nominations. (eg: We'd need to know what rules you use for things like nationality of the author, because that is not always simple.)
For my own purposes I am mostly interested in the first publication date as a matter of context, and more often than not I also look up the author for similar reasons. It's been a habit for as long as I can remember. I've just never tried to graph the results.
