INFORMS was good. It's a big conference and the OR.SE presence was there, but somewhat diffuse.
- The conference had "OR Stack Exchanger" badge ribbons looked good:
- Stack Exchange printed up a bunch of postcard-sized flyers, which were prominently on display in the INFORMS Center in the exhibit hall:
I handed out a bunch of these—maybe other folks did too?
- They also sent a bunch of Stack Exchange stickers, but unfortunately they were delayed in transit and didn't arrive until just before the conference ended:
If anyone wants some postcards or stickers, let me know! I have a lot of them and am happy to mail them to you if you want to bring them to your next conference.
