I admit I haven't read all the posts on this thread, but I do think med school applicants deserve a little more respect. I went through a cycle in 2008-2009 where I spent thousands of dollars, paid for my own travel fees for interviews (compare this to prospective grad students or even some MD/PhD-MSTP students), and sometimes don't even get the decency of a rejection letter. I also think that some of these schools "know," perhaps just based on your numbers and your CV, that you stand a very low chance of getting in, but not only do they make you fill out the automated secondaries, but they don't really communicate to you for months and months... if ever.
I know that they have financial incentives to do this, and given the number of eager premeds every year, they don't have an incentive to make any changes to the system, but that doesn't make it any less frustrating!! But it makes me so sad to see how people who are applying to grad school programs: don't spend nearly as much money/time on applications, don't have to wait as long to hear back, don't have as high a high chance of not getting in anywhere, get PAID to travel for interviews, and are treated so nicely when they do go for a school visit.
