Joining a Zoom (or other video) meeting is as frictionless as opening up the calendar invite and clicking the link. No need to login or do much else, except maybe fiddle with the audio for a bit. "Can you hear me now?" The benefits to this are obvious. But if you're Zoom (or another video conferencing company) there could be a slight problem: I don't really care where that link is taking me, as long as it's taking me to the meeting I was supposed to join 4 minutes ago. In other words, there aren't really any network effects. The service doesn't get any better for me as more people use it, because anybody can join the link that I send them. Benedict Evans recently made this argument, here, and he goes on to posit that video calls, like voice calls, are destined to become a commodity. All that will matter is how you package them up. Makes sense.
