> The people who I know did this missed very important details of meetings, and even has to be clued in that someone was speaking to them.

I agree. Few things annoy me more than having a meeting to discuss an issue. A big discussion occurs while a 1-N people are on their computers claiming the meeting is a waste of time so they need to be working instead. A decision is made and everyone leaves. Later, when the decision is about to be implemented/executed, people who said the meeting was a waste of time now make me re-hash the entire meeting because they disagree with the solution.

I've actually just started responding to these people that they should have paid attention at the time, because I have work to do.
