The Hardest Working Man in Show Business

i would love to hear your opinion of why canva took off. As far as i'm concerned, very hard idid i ersand why? The hardest working man in show business that before it caught on, it needed to catch on. And so how did slack do it? Slack did it really beautifully. Only 500 people needed to use who had the right job titles and could say to seven other engineers around them, we're using slack. They didn't get the i t department's approval, they didn't getting the c o's approval, seven of them started using it.
