Over the past one and a half years, Stack Overflow has lost around 50% of its traffic. This decline is similarly reflected in site usage, with approximately a 50% decrease in the number of questions and answers, as well as the number of votes these posts receive.
The charts below show the usage represented by a moving average of 49 days.
What happened?
Rather than cultivate a friendly and open community, they decided to be hostile and closed. I am not surprised by this at all, but I am surprised with how long the decline has taken. I have a number of bad/silly experiences on stackoverflow that have never been replicated on any other platform.
