What were these pivots like What was different the second time around, Slack vs. Flickr The pivots were hardno one sets out to fail. You dont know, when youre going through shutting down a failed company, that there will be a good outcome on the other side. Whats been different this time around is the growth and maturity of the web as a platformthere are 1. When we built Flickr, the idea of putting your photos online was pretty new. Now the idea of putting them anywhere else is weird. The other big shift is the development of infrastructure and the cloud. The bar to getting started has gotten lower and lower, allowing you to spend less time racking servers and more time working on the thing youre trying to build. What everyday thing are you better at than everyone elseWhats your secret Thats a bit full on. Ive been told I have a tremendous capacity for focused work and high output, but whats allowed me to grow into the CTO role at an org the size of Slack has been my 1. I find in the human aspects of the work. Theres a very prevalent stereotype that engineers are socially unsophisticated, but thats just not the case. Interpersonal communication is an absolute requirement for management and leadership in all functions of a company, and no less so in engineering. Its a team activity. What apps, software, or tools cant you live without Work Slack. News BBC, Twitter. Family Whatsapp, Snapchat. Entertainment Audible, Reddit. Whats your biggest struggle in the workplace Probably prioritizing my time. As an organization grows in size and complexity, its easy to fall into just being reactive. Theres always one more thing coming to you that wants attention and needs to be done now. But stepping back and being strategic about what you focus on is really important. What do you listen to while you work I spend most of my workday in meetings, but when Im working from home Ill plug into Spotifythis week has been a mix of Kanye and British trip hop group Sneaker Pimps. What are you currently reading, or what would you recommend I recently finished Ada Palmers Terra Ignota series, which I strongly recommend. A view of humanity post scarcity and what it takes to hold a society together. Whats the best advice you ever receivedIm not sure where this advice came from, but the idea of finding a set of people you like to work with, rather than the perfect project. We didnt set out to make Flickr, or start a company to make Slack, but finding a group of people that you trust and love to work with means that you enjoy what youre doing, even when you pivot into something completely different. And to drink lots of water and get regular exercise. Whats the greatest idea youve had that you dont want to do yourself I still think that what we were trying to do with Glitch a multiplayer online social game space around would building and collaboration is a great idea. We didnt manage to make it into a successful business and I dont think Ill try doing it again, but the core of the idea was great. If someone manages to make what we were aiming to, Id play the shit out of it. Whats your own Slack etiquette, and how much does it line up with the rest of your team For example, how much do you use Slack during off hours Have you ever made a big faux pas like sending a sensitive message to the wrong channel I think I make that mistake more often with email than with Slack, probably because I use it less frequently. While I read Slack at all hours, I try to avoid DMing people late at night. The pressure for people to respond quickly can guilt people into thinking they need to be always on. Queuing up a bunch of messages to send first thing in the morning lets people know that my questions can wait. Youve pulled off some great stunts, like the who looks like a manager game at Yahoo. Hendersons game asked fellow Yahoo employees to guess which of two people was higher up at the company, based only on their photos. What role have side projects played in your career I had a lot of fun with the early internal Hack Days at Yahoo, showing that you could build interesting projects that werent just a user facing product feature. Playing Game Never Ending the game that preceded Flickr was something I did for fun in my spare time in my early 2. Stewart to come work at Flickr. Fill in the blank Id love to see answer these same questions.
