[Taxacom] The more you know the more you lump|split.

Hi Robin,
 
         Agreed.  But the question is how many of those workers are splitting for good reasons, not simply because they were taught that paraphyly is unnatural and always bad (and that splitting could resolve the so-called "paraphyly problem").  One example of workers splitting for good reasons (based on increased knowledge) might be Platnick splitting spider genera (many of which badly needed to be split), although only time will tell if he may have overdone it a bit in some cases.
 
                     ---------------Ken
 
P.S.  Although most of APG's lumping of angiosperm Orders was a good thing, I am still hopeful that a few cases where they seem to have overlumped them (their bloated Order Poales for example) that they will eventually rectify those examples of lumping gone too far.
