My employer and local school district has had to move to an almost entirely online business model overnight. For myself, I’ve had to learn a bit about Google Meet for the purposes of having meetings and making phone calls, and the teachers and service providers have had to study up on Google Classroom.
Right now, there is a Google Meet and a Zoom conference going on in two rooms in my house, both for school purposes. I completed two teacher conferences yesterday on Google Meet as well. (In true Google fashion, there’s Google Hangouts, Google Meet, and then in a calendar event, you can add videoconferencing and it’s called “Hangouts Meet”.)
Google’s gSuite is free for school districts, so it’s going to be the popular choice there. But other companies, such as Zoom, are enjoying/suffering a boom right now.
Also: try getting a webcam on Amazon. Brutal.
