We've got that channel, and many, many other "help" type of channels, like "help-who-do-i-talk-to" as well as "help" for many different teams, subjects, etc. They work pretty well, but, there's just a lot of communication, and I think the new grads and very young engineers get overwhelmed.

Ultimately, communication between thousands of people is just hard, and technology solutions aren't going to solve all problems perfectly. And again, I want to stress that in general, Slack has been a pretty nice tool. We still just need to do other practices to make sure nothings flying under the radar.
