> I've listened to a Spotify people brag about their A/B testing efforts. It is absolutely crazy how many different variants they have at any given time.
Yeah, I once "decompiled" the Spotify desktop app (it’s mostly a bunch of zip’d web apps glued together), and found details about ad targeting and A/B identifiers. I had 20+ identifiers, most of them regarding ads (i.e. named `ads_<something>`), but also some with weird names like `liar_detective_rollout_Exposed`.
