A few years ago, way back in the late 90s, Citrix Online, the maker of GoToMeeting, was known as Expertcity. They had a service to provide computer help using experts who would connect to users via a browser based screen sharing application. That didn't work out so good so, they pivoted and created GoToMyPC and then GoToMeeting.
Oh, guess what, another iPad story. Score Apple! Everyone else sucks. World domination just as boring as teleconferencing on a hand mirror.
