Watching hoards of people hop on webcams to transmit choppy video information about their face and home seems like wasted bandwidth to me.
Edit: addendum, get a headset, transmitting voice clearly with some decent noise cancellation is really important. I buy the cheap logitech h390, like 25 bucks each.
+1 for investing in a good headset. Get something that completely covers the ears, and/or has some noise cancelling. I bought a Logitech gaming headset with a good mic and it's made a BIG difference, esp. on days where I'm on 4+ hours for calls.
But I'm shouting into the void about that. Most people won't adapt their behavior when it doesn't impact them personally.
I find it awkward and stressful being on the camera all the time.
The latency for phone calls on copper wires back in the late 90s was great, but I am definitely glad that a modern video call doesn't require paying, say $3.00/min/person in the way that long distance did back then.
