Did CLEAR in EWR this morning and it was pretty painless (though the greatest number of people using CLEAR simultaneously I've ever seen -- I think 4 kiosks were simultaneously in use with a more or less steady flow in and out...no actual line though)

Instead of what I've experienced at other airports where the CLEAR "ambassador" personally escorted me from the kiosk to/past the TSA doc checker and presented their SIDA badge, the CLEAR dude at the kiosk waved to a CLEAR woman standing next to the TSA rep who seemed to just be holding her SIDA badge permanently up.

Seems more form than substance, but can definitely see how it speeds the passenger flow through CLEAR rather than making the employees individually escort to TSA, wave badge, walk back)
