  • Any simple/conservative lists that just block ads, not trackers that might break mobile apps and web sites?
    Split.io, segment.io, app-measurement.com, ... These domains do not really serve ads, they are used for analytics which one can argue is a privacy issue. But some Android apps just refuse to start if you block some of these domains. Source: almost 4 years ago
  • Dev is painfully slow
    People here must not be using Animation libraries, or A/B testing libraries (ala split.io) etc.. These bring in hundreds of modules alone.... terrible, but I'm thinking many of those posting aren't really building for serious enterprise production type websites. Source: about 4 years ago
  • What words do you like to put on your buttons?
    I looked up split.io and their website is worse. I see some technical jargon that I recognize, but the rest is gibberish. Makes me think there is room for providing better content in the space. Source: about 4 years ago
