I guess, yes, there is a benefit to Slack in the sense that they would have more signups overall. But what I was really going for was that it wouldn't benefit them on a large scale, meaning that people that do stuff like what he does would have to move to Slack, which is most likely not going to happen without large incentive. I doubt that he has enough "clout" to drive a noticeable number of people to Slack over a long period of time. The only way that this would change is if Slack marketed itself differently.

Yes, but Slack isn't really built for some of these purposes and it shows in the way that people see each other within the app. I.e. I see all of my coworkers within Slack, which is not what you want with tech support. I can see it being useful for a student-student interaction, but it would have to be augmented to allow specific student-teacher collabs because all people (at least in the way I understand) are on the same "level" and can see everyone and all the channels, which might be counter-productive to learning because it becomes like AIMing your classmates at that point.

Thanks dude! When I use the Internet next time I will be sure to think about this comment. :-)
