It's kind of hard to predict *which* tweet will anger people. The best filter is to ask: what sort of people are going to want to react? You don't want the answer to be "political activists", for instance
Many people see Twitter as a game where the goal is to dunk on others in front of an audience and get likes as reward. It almost doesn't matter what you say -- it's all about how it gets framed.
A framing of my tweets I've seen maybe 5-6 in the past few weeks: "dumb tech bro is trying to reinvent my field, let me immediately assert intellectual superiority". It's funny to me because I'm usually just posting whatever I'm currently thinking about -- spurs of the moment.
As for the "tech bro" part, no one who knows me would describe me as one, but having "Google" in your bio instantly earns you that label. Again, framing.
I don’t have tweets that gained many likes, I don’t know that is a thriller or how does it feel haha... only when I tweet foreign politics, I got some responses back. Otherwise, quiet as night, no likes no responses
