On the shoulders of giants
We love Medium, Pinterest, and Flipboard and are greatly inspired by them. The universe image we use on landing pages is by Jeremy Thomas, found on Unsplash. We use many icons from Font Awesome. Also, we highly recommend the Noun Project. We’ve found a number of great icons, including the robot by Aaron K. Kim, the message icon by Dinosoft Labs, the ellipsis icon by David, the headphones icon by fizae, the plus icon by Three Six Five, the bell icon by creative outlet, the coin icon by romzicon, the brain icon by Nikita Kozin, the banana icon by iconsmind.com, the quill icon by Hea Poh Lin, the loop icon by useiconic.com, and the sun by Andrey Vasiliev. For some mocks, we use a modified vector image by frankmib6, found on Vecteezy. Also, we love Raul Taciu's beautiful social icons. The firework effect at the bottom of your feed was made by Jack Rugile. The placeholder colors are inspired by Van Schneider’s unique color pairings. And the lovely zoo animals we use for groups are designed by Freepik.
We write our backend mainly in Ruby and host on Heroku. We don’t use Rails but Sinatra, we use Postgres and Redis, and Sidekiq for background processes. We use a number of tools such as Librato, Skylight, Airbrake, and Logentries, and a host of gems, such as Twitter, Markio, and Pocket. Our crawlers are hosted on Joyent but we also use Mercury. For some high-performance tasks, we use Rust. We use CloudFront as our CDN and S3 for some parts.
Our mobile apps are hybrid at this point: we write the native parts (share extension, offline access) in Swift for iOS (using many Pods) and in Java for Android. We’ll go all native down the road.
We use git and store (most of) our repos on Bitbucket.
We’re a tiny team and work mostly remote. We use Trello, Slack, Appear.in, and sometimes Google Docs.
