I feel like I'm in some bizarro world here. Maybe SDN self selects for the people who intentionally avoid social contact, but I don't understand the ire directed towards Match Day ceremonies. Barring the unfortunate incident of someone not matching, the match day ceremony (whatever your school chooses to do) is a pretty fun experience. Nearly 4 years (or more, depending on how you look at it) of your lives have been leading up to this point. The vast vast majority of my classmates were very excited for Match Day, and this whole "too cool for school" attitude was nowhere to be found.
Maybe SDN has built this counterculture where caring about things isn't "cool", I don't know. Granted, my school didn't have people announce their match results, we just got called up on stage (while a 30 second clip of whatever song we chose played in the background), received our envelope and shook hands with the Dean or whoever was handing them out, dropped a $1 bill into the pot, and returned to our seats with our classmates/loved ones to open the envelope. There were varying degrees of "sharing" (a few loud outbursts of joy, more often slightly more reserved excitement). It was all a very social event and the camaraderie was fantastic.
I guess if you're one of those people who hates your classmates and thinks you're above sharing this fairly monumental event with them, the decision to abstain "makes sense", although I wouldn't agree with it.
To medical students/pre-medical students reading this thread: keep an open mind and try not to blindly follow the vocal minority here who keep trashing Match Day. Looking back on it, it was a great time. I agree with the other posters who said that Match Day really felt like the culminating ceremony to celebrate finishing medical school, and Graduation Day was almost an afterthought.
