I find instant communication useful for quick "Am I doing this right?" problems people have. Sending something like "I'm getting ssh connection refused while trying to connect to this host. Can someone else try?". That can quickly be answered by multiple people and people can chime in their quick thoughts for what is likely the problem. Trying to communicate a bunch of people with one line question/answers would be super annoying with the latency that email has.
