2. Be polite to the speakers
The second rule is: you agree not to be rude to the speakers.
You are, of course, allowed to dislike or disagree with their talk! In every event, you will probably find one presentation that doesn't work for you. That's normal. But it is not acceptable to insult speakers, demand multiple times that they answer your question, or post derogatory remarks in the chat.
This includes repeated, dramatic proclamations that the talk is too hard to understand, not what you expected, and so on. It's obviously fine to ask for clarification, definitions of terms, or a repeat of a key idea -- we are all learners here. But sometimes a single participant can talk so much about not getting the speaker's point that it becomes disruptive for everyone else.
I will politely remind the room of this rule if I see attendees breaking it what seems to be an absent-minded fashion. It's natural to ask for help in an educational event like this. However, people who are being rude maliciously will be removed from the event.
Complaints about the speaker's looks, vocal mannerisms, speed of delivery, accent etc are definitely included in this rule.
In addition, "compliments" about the speaker's looks are not acceptable during the summit sessions.
Of course, all of this is not to say you need to be a silent participant. Feel free to speak up, share your thoughts, and if there a tech problem you've noticed, mention it without hesitation! -- "You're still muted, speaker!" -- that's obviously fine.
For example, if the text on a speaker's slides is too small for you to read, please tell us ASAP. We will try to find a real-time solution.
On a related note (rule 1.1, perhaps): we should try to keep conversations in the chat relatively on track and relevant to the speaker's talk. Making quips, greeting other participants, and throwing out side references is great; getting into an argument with other attendees about a minor factual detail or your own pet theory is not okay. Similarly, sharing links to your own writing, blog etc is not banned, but not allowed while the presentation / interview is going on. Please wait until the Q&A portion or one of the happy hours / networking sessions.
