It's rare that I make it all the way through my Duolingo practice session without needing to look something up, or making a mistake. But when this came up I had a *good* feeling...
I have to actively fight against that here. Those who "walk over and talk to someone" often fail to share the results around the team's other members. Emails on a mailing list do that automatically.
I understand f2f bandwidth is higher, but it's a major issue in split teams.
