As someone who you would probably accuse of the above, I think the real
problem is people who read papers and accept the results uncritically.
You can only state that your own results are crap to a certain degree
before it becomes painful.  And if your phylogeny is reasonable and is
not likely to be improved on, then it's what you've got to go on for
biogeography and such.  Just because you don't have a perfect
phylogenetic hypothesis as your basis doesn't mean you should just
completely ignore it.

Point taken.  Then again, I'm a grumpy young man, whose dissertation
ended up with a weakly supported phylogeny with almost no hope for
improvement.
