Slack lowers the friction involved in communicating. Depending on the kind of communication that it is, maybe that's bad or good.<p>In many corporate communications platforms, it is quite effortless to ask an idle question, use an emoticon, paste a giphy image, write a bot to push notifications into your team channel, express a witticism, or vent complaints. It was my experience that Slack made it easier to do all of these things more than any platform I'd previously used. I've been off of it for 3 months and hope I never have to return. The worst problem seemed to be the number of ad-hoc channels I could be automatically invited to, and it was not often clear whether the information exchanged there was something I needed to pay attention to (although in retrospect it is more so).<p>Different organizations will utilize it differently, and feature-wise Slack seems to have gotten pretty far ahead of the competition. But if there's any truth to the medium being the message, then I think that it can be inferred from much of what transpires on Slack is that as a platform it is a big time sink. There don't seem to be a lot of important degrees of urgency between an email, a phone call, or a drop-by. For me about 90% of the value in corporate messaging is pasting web links to resources, which doesn't require the other bells and whistles.
