This is awesome & good news in every way. A lot of the comments here seem to really circle around how people treat instant message communication vs e-mail and/or being inundated with being a part of multiple Slacks. If you are blocking co-workers like one person mentioned or muting them, you have other issues (yes, you can mute a user) If you're demanding or need instant communication with someone, just call them from Slack. Or, alternatively, make sure you '@' them properly & force a send notification. The issue I see is that not everyone is all about real time comms -- some people put Slack on their phone or on multiple machines. Some don't. Some people claim it's buggy -- I've had far more issues with HipChat just when it comes to displaying on two monitors than I have ever had with Slack. I saw a few people complain about productivity sinks but the reality is if you want to be a part of a certain group to keep up top of what's being discussed, that's the pulse & one way to do it if you have a large amount of brain power in the room. Meh. I'm excited.
