Just read the tweets from last night. There were two people who actually went to the bathroom during the concert so they could use their phones and tweet. Obviously completely addicted, and kind of sad IMO. One person complained about not being able to stand up and dance, another said it was the first concert they'd ever sat down for and it was kind of nice for a change. There were a lot of tweets that said the place was far too warm. Of course, nearly every tweet said the band was awesome.
