This x2.
I've got my ticket to the 2005 and 2008 openers, Strasburg, Zimmerman and Harper's first home games, last years playoff matches and more framed above my Nat's 'shrine.' I saved *every* ticket I went to, tossing them in the STH box they came in as a momento. It also serves to let me know what games I went to. I can dig in my 2008 box, see every game I attended that year. If the ticket ain't in there, I didn't go to the game.
Losing physical tickets is a loss, no matter how inconsequential. The card is of no benefit to me, I'm not the type logging online everynight to check whatever promos or discounts they load on to it. Maybe some prefer it, find it advantageous. I don't, and won't. Hell, I liked being able to look when I ripped out my ticket for that night's game to see future matches and times. Last game of the homestand, I took a glance to see the next date and time, referring to it as a 'schedule magnet' throughout the season. For some segment of fans like me, those that don't check e-mails and Tweet or Facebook every 20 minutes, this is a net negative.
It'd have been nice if you could opt out and pay them however damn much they wanted to get a physical book of tickets for STHs, but c'est la vie. Over and done with, but that OD commemorative ticket was definitely proof they completely missed the point for some of the fans.
