Best part about Zoom and similar programs is that you don't have to deal with the horrible Skype search feature for everyone in the call before starting it. Why can't people find me by my username? Who knows. Why don't I see people online even though I know they are already, forcing both of us to message each other before we can start a call? Who knows.

With Zoom and other conference programs, callers just join the call (after they've downloaded the program which admittedly is an initial pain point).
