Also biased! [0], we use them a lot, mainly on the front end. Most of the new features we are working on are gate-able via front end UI elements, and so we push out pretty much all our new features using our own platform. We are also doing interesting stuff like controlling what features are in our Open Source Docker container via flags in the platform that are baked into our Docker images when they are built. Once you start using and relying on flags, it's hard to go back, and helps with a bunch of 'good' engineering processes and patterns. Another interesting aspect is that once you have gated a feature based on a flag, you can then AB test that feature, almost for free, as you have a way of bucketing users and showing or hiding the feature using most feature flag platforms.
