I, too, was in the cancellation line on Wednesday.... We all clapped when you got your tickets! I ended up getting tickets through stubhub because they were fairly cheap (by hamilton standards!) and would not have gotten tickets otherwise.
I'll add a couple things here...
1. I don't think the cancellation line is going to last as it is much longer. We were moved 3 times back and forth so that roads could be cleaned and cars could get into the small spot fenced in by the theater. There were two line holding companies there... one had a guy who basically tried to run the entire line and then cram in two more people at the end... then he decided to create a thursday line after people had already created one (of course, the line really should be whoever was left over from the wednesday line and still interested). . This guy was also tweeting bad things about the people in front of us in line the whole time - although i wasn't paying attention maybe they deserved it. The other line-holding company (Same Old Line Dudes) were awesome guys, friendly, talking to us the whole time.. even telling us secret places to charge our phones or take a pee. I stayed away from the politics developing in the line - strange stuff with people disappearing and reappearing - there were always people in line but somehow they seemed to get a lot more tickets than 1 spot should get.
2. I got there at 5:30 am... I was 16-17th in line. First show, 14 tickets were given out (including the 2 for the night show). I was up to 7th in line for the night show (not really any drop outs) which meant 13th ticket. I ended up getting a pair off stubhub for $400 each so I left the line - this occurred around 5:30pm, or else I would have been out of luck. Stubhub ticket center was 8 blocks or so away but it was easy enough to get there and back. I heard only 7 tickets went up (almost all to lineholders) for the second show but I wasn't there to confirm it. I do know the nice woman in front of me from LA did not get tickets. She had gotten there about 4am I believe she told me.
3. The cancellation line (according to veterans) has almost doubled in length the last couple weeks. It's a far cry from being almost a guarantee if you show up 5 hours early. The people in the line were really cool. I think we all had some sort of theater connection in someway so you got to hear some great tips on other shows and stories. Daveed came out between shows and was awesome, taking pictures with all of us.
4.For the matinee, the first pairs of tickets came two hours before the show or so... everything else was right at the start of the show. There was one obvious scalper selling fake tickets but I didn't even see any real tickets being sold or given.
In summary - the line holding companies are taking this over... the whole "thursday line starts when we say" thing was lame... and they were holding multiple spots in multiple lines for multiple people at once. This is no longer a guarantee. I heard a ton of people complaining to people at the show and city as well so I think they will be forced to end this practice and do bracelets or something before too long.
