(reposted from the Stack Overflow blog<\/a>)<\/p>\n

2010 was an absolutely amazing year here at Stack Overflow. We grew from 7 million visitors to over 16 million, putting us in Quantcast\u2019s top 400. We raised $6 million in venture capital, and we went from three full time employees to 27. We built a 7500 square foot office in New York, and we launched a ton of new features and sites, like Stack Exchange, a network of 33 Q&A sites on diverse topics from cooking to computer science. Stack Exchange grew 51% in December alone. Wow.<\/p>\n

The expert Q&A model that Stack Overflow pioneered is really working. The statistic I\u2019m proudest of is the percentage of questions that get a good answer, over 80% (and many of the new Stack Exchange sites have 100% answer rates!)<\/p>\n

Traffic<\/h2>\n

The true measure of success for any Internet company is how often people come up to me in swank hotel lobbies and offer to buy me meals, let me use their corporate jet, etc. But since there is a great deal of disagreement as to how to measure that, we track a reasonable proxy called \u201ceyeballs,\u201d on the theory that if a site is useful, people will load it up in their browsers and eyeball it.<\/p>\n

\"Traffic<\/p>\n

Traffic to Stack Overflow grew 131% in 2010, to 16.6 million global monthly uniques. *Uniques* are counted by cookies, so the number of human beings is less. We also measure the number of page views (top level pages loaded, which doesn\u2019t count images and supporting files), which has similarly grown from 31.8 million per month to 72.8 million per month, i.e. 129% growth.<\/p>\n

Based on the number of people who do come up to us in hotel lobbies, we\u2019re pretty sure that ALL the programmers in the world use Stack Overflow. (Source: completely made up. But seriously, when was the last time you met a programmer who didn\u2019t use \u201cEl Stack\u201d?) In order to keep growing and making the Internet more awesome, we have to expand into new subject areas, like Molecular Biology and Harley Davidson Belt Buckles. That\u2019s what Stack Exchange is all about. Stack Exchange growth is insane. In six short months, we\u2019ve gone from zero to 1.5 million monthly visitors, growing 51% in December.<\/p>\n

\"2011<\/p>\n

\"SceneIf, as planned, we continue growing at 51% a month, we will be bigger than Facebook in 15 months. We\u2019re ALREADY bigger than ocn.ne.jp (No, I\u2019ve never heard of that either. But we\u2019re bigger). Jeff and I are already planning who will play us in the Aaron Sorkin movie. (Tyler Labine and Zac Efron, obviously.)<\/p>\n

Now, obviously, all this TRAFFIC isn\u2019t worth a thing if people aren\u2019t getting answers to their questions. That\u2019s why our favorite thing to measure is \u201cpercent of questions answered.\u201d And not just any answer will do, either: to count a question as \u201canswered\u201d, either the original poster has to accept the answer, or a third party has to upvote the answer. This is where Stack Overflow really shines compared to other Q&A sites: we actually get questions answered. Three of our sites actually have 100% answer rates!<\/p>\n

\"Chart<\/a><\/p>\n

New Sites<\/h2>\n

Last summer, we relaunched Stack Exchange as a democratically-driven network of sites on topics chosen by our users. Some of these sites are directly related to programming (for example, <\/span>Game Development<\/a>), but some are quite far afield, from <\/span>English Language<\/a> <\/span>toCooking<\/a>.<\/p>\n

\"Screenshots<\/p>\n

We call it the Stack Exchange network, and at <\/span>StackExchange.com<\/a> <\/span>you\u2019ll find a directory of all of them, along with some hot questions, statistics, leaderboards, and other tools so that you can follow the sites and tags that you\u2019re interested in.<\/p>\n

We learned a long time ago that the only way to get questions answered promptly is to have a critical mass of knowledgeable users, so we have an onerous process called <\/span>Area 51<\/a> <\/span>where sites are proposed, discussed, and voted on. If a proposed site doesn\u2019t have critical mass, we just won\u2019t create it. Even if it does get created, it has to maintain a certain level of traffic and quality or we\u2019ll close it down.<\/p>\n

So far, 13 sites have gone all the way through the Area 51 process and launched. Dozens more are already in beta. Hundreds more are in active discussion and will launch when they reach a critical mass of interested participants.<\/p>\n

The development team has been knocking out new features at a constant pace. They built an amazing web-based chat system, and we\u2019ve added literally hundreds of new features and improvements to the core Stack Overflow engine which we roll out continuously.<\/p>\n

The Company<\/h2>\n

At the beginning of the year, Stack Overflow LLC was just three developers working from home. In the spring, we raised $6 million in venture capital from Union Square Ventures and a long list of celebrity angel investors, which allowed us to expand rapidly. We hired a team of great people, including several of the high-reputation users that you know from Stack Overflow.<\/p>\n

\"the<\/a><\/p>\n

\"\"<\/a>We now have community managers, a sales team, two full time system administrators, and Very Important Administrative Overhead like myself, but most importantly, we have a great team of developers, in New York and around the world, building the next generation of cool features, like the important \u201cwheel of blame\u201d feature, which we can run at any time to calculate precisely who is responsible for anything that went wrong. (Contrary to popular belief, it\u2019s not always Jason Punyon.)<\/p>\n

To make room for all these people, or, at least, those who live in New York, we rented a 7500 square foot, class A, super-elite batcave in New York and then fixed it up to be nice, with cool furniture including Aeron chairs and height-adjustable desks, and lots of glass to bring views and daylight deep into the batcave. And of course, we have private offices with a half dozen gigantic 453-inch monitors for each developer. And there\u2019s an amazingly cool Star Trek couch. Does your company have a Star Trek Couch? *I didn\u2019t think so.* We also have <\/span>Rovio<\/a>, a little robot that our remote developers can use to visit the office \u201cvirtually.\u201d (There. I said \u201cvirtually.\u201d Are you happy now?)<\/p>\n

\"Floorplan<\/p>\n

Overall 2010 has been a real breakout year for Stack Overflow, which is now the largest programmer website in the world (source: me) and the best, fastest-growing Q&A website in the world (source: also me). We\u2019ve got an incredible team firing on all cylinders, so we\u2019re really looking forward to 2011.<\/p>\n","protected":false},"excerpt":{"rendered":"
