dutchman, matchlist isn't some "stuff [that] is completely meaningless."
In fact, schools do advertise their matchlist. Many of them have have them on their websites. Also, when I visited Yale, they gave me their matchlist to look at. And boy, was it impressive. And I haven't looked at Harvard's matchlist, but I suspect their matchlist is better than all the state schools in the US except for UCSF, which probably is comparable.
I also don't think US News is completely meaningless. I think there is some value to it. It is hard to rank some schools i.e. you can't say that because Duke is ranked lower than WashU this year, WashU is the "better" school with confidence. Having said this, ranking does give you a pretty good picture of tiers of schools. And reputation of med school does matter when you are applying for residency.
Of course, matchlist and us news ranking should not be the sole factors on deciding med schools b/c there are other important things as well such as money, environemtn, curriculum, school's focus. But these two should be definitely looked at. I bet 99% of the SDNers have looked at and do know rankings of their schools on US News anyway.
