To add to the tools already mentioned in the thread, we use
- Fabric to deploy
- Asana for task/project management
- Google Analytics and KISSMetrics
- HipChat (with hooks into GitHub and our Fabric Deployer)
- AWS SES for sending emails out
- Git flow (Just looked at GitHub Flow, looks something we can use.)
- With the reduced rates of SQS, we plan to use that. We used RabbitMQ in the past.
