While I'd like to be as brave as those who can resolutely remain seated during SO (esp you, whoever didn't stand up for Boy From Oz in the front row! lol), I'm a weenie and bend to the implied peer pressure to stand when everyone else is shooting glares at me for not thinking the Miss Saigon tour and Blast were worth SOing over. But if I was in plain view of the performers, I might stand, out of support for them. I worked for Cirque Du Soleil last year and I felt so badly for the performers who notice those few who don't stand and bitched about it backstage afterwards. But hey, it's nice to have a bit of humble pie.
On the flip side, how many people are comfortable being the first to initiate a SO? Because not too many people will notice you if you don't stand, but EVERYONE notices the one guy who stands and cheers amid a sea of bored faces that are all thinking the same thing: Gee, this guy is too easy to impress!
