@Zaktor@bluGill No. A lot of meeting could better have been e-mails or a chat message, but they are still slower than direct communication. Usually people have switch off notifications so they are not distracted by all the emails coming in over the day.
Meetings also synchronize the team which important to give everyone an overview. All are concentrated on the subject (if the meeting is short). Furthermore, it is a ritual. And ritual are important for human beings to structure their day.
