Formal and/or scheduled meetings are not the only and often not the most effective way of communication between team members. Highly effective teams often have a lot of informal interactions between team members by various means of communication not restricted to one-on-one talks or small group meetings before white boards. I know many introvert developers that rather write a detailed comment on an issue raising some discussion points than have a discussion on the subject. In a highly effective team, the team members know the strong and weaknesses of fellow team member and are often able to arrange things without having to rely on regular scheduled meetings and/or stand-ups.
