The Real Lessons From Twitter

Posted on : 17-06-2009 | By : Tony Stubblebine

In 2006, I was the director of engineering at Odeo, a podcasting startup notable for birthing a side project now known as Twitter. My major contributions were doing the statistical analysis that showed that our podcasting work hadn’t amounted to a hill of beans* and then not complaining when our most reliable engineer wanted to work on a side project. Still, it was fascinating to be in the building during Twitter’s conception and then to read all of the ways that people misunderstood those early days.

Here are three lessons I learned from Twitter that nobody seems to have caught on to.

1. If people use it, it’s valuable
Have you ever looked at a piece of social software and thought, or worse, blogged, that it was worthless? Here’s a trick for evaluating social software in a way that isn’t going to make you look stupid six months down the road: assume it’s valuable if people are using it. Then try to figure out what value they’re getting.

Even professionals make the mistake of dismissing social software despite active, growing communities. Consider this early TechCrunch article, Dodgeball vs. Twitter, where the author (not Arrington) insists that the way to compare software is feature by feature. Dodgeball won the comparison but within a few months was in the deadpool and now Twitter is part of TechCrunch’s everyday coverage. Why? The features that mattered were defined by social interactions, and each user had their own customized set of features based on the social interactions that were important to them. Dodgeball had more features by the traditional measure, but Twitter had the kind that mattered, loads of social interaction.

I even find that this is a good reminder for myself. I follow a startup advice blog from Eric Ries, cofounder of IMVU. The first time I heard what IMVU did I thought it was laughably stupid. They make 3D chat rooms, (like a mini Second Life without the flying), and make money by selling virtual clothing for people’s avatars. Yet he is able to explain IMVU with a straight face and then seems genuinely surprised when people express skepticism.

Here’s the reason he can keep a straight face: IMVU gets 1.3M unique visitors a month and makes tens of millions of dollars per year. He’s not judging the idea based on opinion, which is where most people get into trouble, he’s judging based on observation. Now, I feel stupid for not keeping an open mind.

2. Product, Team, Market? Team.
This is a fun little debate, what matters most the product, the team, or the market? At the time that Evan bought Odeo back from the investors, our podcasting product was widely seen as a failure. It didn’t have any growth and it certainly didn’t make any money for the investors. Here’s how Bryce at OATV put it:

Rockstar team, smoking hot market, all-star angels — and it didn’t deliver the hyper growth traditional VCs need for their return profile.

Was it the product? A year after Ev bought Odeo back, and after zero updates to the features, Time Magazine listed Odeo as one of their top fifty websites. Today, with a very similar product, is the only podcast directory of note. So the product was fine.

Was it the market? Marc Andreessen argues that the market is the only thing that matters for a startup. I just made the argument that Odeo was a strong product and I’m going to argue below that we had a strong team. Since no other web based podcast directory has proven otherwise, it looks like we were in a weak market. So is the answer that the market matters most?

That would look like the answer if not for Twitter, that pesky side project we launched that has had 10x growth in the last year. Market only looks like a good answer if you’re judging individual products, in this case the podcasting directory.

A good team, that listens to its customers, is going to find a good market and put together a good product for that market. Steve Blank calls this process customer development (explained well in his book Four Steps to the Epiphany and in this Venture Hacks post).

We could see that didn’t have enough traction so we went looking for other ideas. You might think it was lucky that we hit on Twitter, and as a specific product, it was. If Jack wasn’t on the team, there would be no Twitter. But the team at Odeo had lots of ideas and plenty of people capable of carrying them out. Of the 19 or so people who contributed to Odeo, 13 had started or went on to start a business or major open source project**.

If Ev hadn’t bet on Twitter he would have bet on something else. Three of the companies above are currently live companies that support their founders and a few employees (Infectious is funded and doing well, Trazzler is funded by the Facebook fund, and CrowdVine is profitable). I chose a vertical route for CrowdVine, but the original idea, social networks for everyone, is an idea that’s nearly as big as Twitter (as evidenced by the size of Ning).

Because of the team, Ev had other options to overcome a weak market. So if you’re looking at it from the perspective of the company, team is most important***.

3. Rails was never the problem
Twitter had well-documented performance problems in it’s first few years. Many people, including programmers, pointed the blame at one piece of Twitter’s architecture, Ruby on Rails.

First, all Rails does for Twitter is serve up web pages. The vast majority of those scaling problems came in the back end, moving status updates around and then storing them in a way that Rails could retrieve them for display. So most people aren’t even looking at the right piece of the architecture.

Today Twitter has a much better performance track record and it still uses Rails to serve web pages. The difference is the backend.

So if the backend was such a problem why didn’t Twitter launch with a better backend or at least get it fixed earlier? That gets at the heart of the problem. I’ve never heard anyone get the blame right for all of those performance problems. They stem 100% from the way that we went about switching from the Odeo product to the Twitter product.

When a company kicks off their first project they do some long term thinking and might cover topics like architecture. But how do you launch your second project? Or fifth (approximately what Twitter was)?

Was it easy for the Flickr team to choose to double down on photo sharing, which initially was just a feature inside of a web-based multi-player game? For us, it wasn’t an orderly process at all. It wasn’t even clear that we were abandoning Odeo. We were running hackathons, which led to a condition where many people had competing ideas (and implementations!) of what our next product should be. But around those hackathons we were still continuing to develop Odeo. Twitter eventually won enough that we pulled two engineers off of the Odeo team, but the rest of us kept plugging away.

If you were thrown into a fight, would you start punching or would you open up your iphone and start browsing web pages about Karate? I’d argue that Twitter was launched in the middle of a fight for what we were going to do next, and any thought for long range planning was completely secondary to getting Twitter launched and proven. Without Rails, we might not have even given Jack time to finish the prototype.

So that’s why Twitter wasn’t ready to scale from day one. However, it took almost two years until it could scale reliably, and that certainly seems like longer than necessary. I think it’s an issue of engineering management. Until the Summize acquisition, there was no true engineering manager for Twitter. I had left before Twitter was spun out****. Everyone was a little wary of hiring middle management again since it was widely seen that we had been hired too early at Odeo. The job of middle management is to promote forward progress, and it took us awhile to figure out that wasn’t what Odeo needed. Twitter did eventually hire a VP of Engineering, but he didn’t pan out.

The result was that Twitter operated for a long time (until Summize was acquired) with a gap in engineering planning, someone who could put together a plan that everyone understood and could work from. They had people who could solve problems in brilliant ways, but they didn’t have someone who could get the entire company on the same page. That gap was just an unfortunate side effect of the jumbled team that emerged post-Odeo. So what’s the right way to change your company’s direction? It certainly had nothing to do with Rails.

* Odeo was eventually acquired and is today the only podcast directory of note. However, as a venture backed concern all we had really managed to build was a site with high page rank. We had terrible numbers on repeat visitors and our experimental features (podcast studio, send me a message, audio commenting) weren’t getting any use. Maybe we could have gone after libsyn’s podcast hosting business, but overall our stats said that if we wanted to strike out in a new direction we shouldn’t feel constrained by podcasting.

** Those remaining six include a former core contributor to Rails, Twitter’s current support lead and people that worked for Apple, Google, and Flickr.

*** The idea that Twitter is the same company as Odeo gets muddied because Ev bought the company back, laid off a chunk of Odeo and reincorporated Twitter as it’s own company. But I’d argue the difference isn’t important here. Twitter was launched and run in the early years by Odeo employees who worked at the same desks and the same office that they had when they were working on

**** People often ask me if I regret leaving, and I don’t. I made a list of reasons that included several that would have been sufficient on their own. Did they need me? Not at first, and I hate being idle. Was I happy? No, I was miserable. Every month I had told my team that what we were going to work on was critically important. And every month it had ended up not being important. It taught me an important lesson about what I want from work, to walk in every day believing I’m doing something important. I ended up with the opinion that the only way I could guarantee that was by owning my own company, hence CrowdVine.
