I like that I can participant in virtual events in Zwift that I wouldn’t be able to in real life such as this morning’s El Giro de Rigo.
It is disappointing when a special guest like Rigoberto Urán doesn’t message anything during an event - no hello, no thank you, just silence.
I feel Zwift should provide some coaching and nudging to avoid silent special guests.
I guess the ride was to hard on him, and he wasn’t able to type on the keyboard 
Poor guy 
But then again, can we be sure that it is the riders themselves that write the comments? I have seen comments from riders, that clearly is not written by them, as they, at the same time, was on webcam clearly not writing on keyboards or smartphones 
Was he the “official” group leader? If not, I believe there is also a distance factor. I don’t know for sure how this event was set up, but, in other group rides, you can only see messages from riders “near” you. If he was in the ride I did, I’m sure that would have only been for about 30 seconds at the start for myself
