> 4 billion actions but none of those are mine Some of them almost definitely are. Half the benefit of Mixpanel is tracking how people use your web and mobile apps. HN could be using it. "User kijin logged in. User kijin viewed a story. User kijin commented on a story." -- all these events can be sent from the server to Mixpanel, then you can build ad-hoc reports on things like "how many users that read a story last week came back and read a different story this week". You can't block that kind of tracking, it's not happening in your browser, but it's just as specific to you. Mixpanel has APIs for server-side tracking in all the popular languages and all the mobile platforms. Every website you log in to, every Facebook app you interact with, every game you launch on your phone could be sending all the event data to Mixpanel and you wouldn't know.
