It does seem a bit quieter (perhaps thats because there's no "setlist party" thread officially (yet) - though its kind of nice... when there are dozens of posts per minute, it gets hard to keep up...
As for yesterday, I was only in and out, but from what I gathered, there was a lot of complaining about the lack of changes in the setlist and some "Vertigo tour sucks," too, IIRC.
From a setlist-watching standpoint, I can understand disappointment. But IMO there's a big difference between watching a setlist arrive and actually being there. I, never having seen U2, would be perfectly happy to get a bunch of "greatest hits" songs - Pride, Streets, NYD, One, etc. even though I'd much rather see setlists that feature things like An Cat Dubh or Who's Gonna Ride Your Wild Horses (of course I'd be blown away if I ever actually saw those gems)...
Twenty minutes, give or take! Will they start with Vertigo today? I think they were working on a couple of openings on Thursday(? or was it Wednesday?) one with Vertigo and Until the End of the World, and one with Vertigo and All Because of You. I'm expecting the latter, especially of they decide to play Wild Horses, which would make much more sense in the encore.
