"weakest" devs - you know not everyone is outspoken and will communicate without issues, new young devs will be afraid to ask an experienced guy. Some experienced guys (also "weak") will be assholes to young devs for asking questions. Just getting team to talk to each other at least once a day is positive. Unless you work only with senior people who are experienced and don't have any issues talking to each other, I would still try to get people to gather for standup.
