"In this study, we compare the GENETIC classification with the expert-based picornavirus taxonomy and outline differences in the underlying frameworks regarding the relation of virus groups and genetic diversity that represent, respectively, the structure and content of a classification."


And they make the rather breathtaking statement that:

"Virus taxonomy has received little attention from the research community despite its broad relevance".

Really, guys?  As a longtime member of various ICTV committees, I have to say the bovine excreta content is high in this assertion...  But otherwise, a welcome addition to the taxonomic debates.
