I'm a remote employee and the absolute zero feedback you get from presenting in an empty room to a laptop webcam is real

The flood of smile thumbs up and confetti emojis on slack and Google meet isn't enough?

Watch your next demo day meeting... Some people will get tons of reacts, comments; some people get nothing. At least in person you get the obligatory smattering of claps after the talk. When there's nothing at all, it feels like you did something wrong.

Is it possible for you to challenge the status quo?

For example, refuse to present anything unless at least three members of the audience agree to share their feedback in the session.

Or alternatively, include in your presentation direct questions to specific members of the audience (either pre-arranged, or spontaneous).
