Can I still somehow complete the quest, or am I just boned?
It wouldn't hurt to try entering the chat now, and see if the quest is still unlocking for people. A few people joined the livestream very late last night to get the quest, if my memory's right, so the quest might not be switched off.
Not that I necessarily think it would just switch off like that, as it doesn't appear to be a limited edition quest set.
Do I have to create another profile on Screened or Justin TV???
Edit: Well, Screened has a similar quest (I Was There), but it is not the same one. And it appears Giantbomb doesn't have any video archived about the premiere. Maybe Justin TV is really the answer, but should we register there too???
