How have I never noticed the love /hate hands in the screen before?
You mean...the Hands of Love. 
Coolest part of the show for me! Nice reference to a film. Exit was phenomenal!
Takeaways:
1) u2 security millennial stole the encore on periscope. He told his friends "I'm just working a concert for some band my parents like..."
2) we finally got to see acrobat on stage...what was with the handstand guy?

So thats what that was? Did Larry play the drumroll?
Yep he did. Weird way to end a show... is this the first time they've dropped the last song on this tour?
I had a great time last night, even though the people around me weren't into it and kept talking/checking their phones, which was kind of distracting. Also the lights stayed on in our section... I didn't get that... Hearing The Joshua Tree was so worth it though. Especially my favorite U2 song, One Tree Hill, which I never thought I'd hear live.
What was the film clip that introduced Exit? I've been wondering that since last night. Also wondering all the things Bono said onstage, because I couldn't understand half of them (and having one of the people beside me constantly asking me what he was saying didn't help), but listening to a stream of the next show would probably clear that up.
