Weigh in is for anything people should take a side on. Pick its form, and the three sides people choose from are worded to fit it.

Steps

Tap the round + at the bottom of the screen.
Under ASK PEOPLE TO, tap Weigh in.
Pick its form. The box tells you what to write.
Write it.
Check the three sides. Leave them, or tap one and name it your own way.
To post without your name, switch on Post anonymously. See Post anonymously.
Check the line at the bottom — “Goes out as a confession · Same / No judgement / Not me”, for example — then tap Post.

The seven forms

Hot Take — the take people will argue with. Sides: Agree · Not sure · Disagree.
Confession — what you want off your chest. Sides: Same · No judgement · Not me.
Question — a question for the yard. Sides: Yes · Maybe · No.
Pick a Side — the two sides people choose between. Sides: With it · On the fence · Against it.
Prediction — what you think will happen. Sides: Will happen · Not sure · Won’t happen.
Story Time — the story. Sides: Believe it · Hmm · No way.
Debate — the motion. Sides: For · Undecided · Against.

The card shows the form at the top, so people know what they’re answering.

Change the form and the sides change with it — unless you renamed them, in which case your words stay.
Taking a side is one tap. See Take a side.
After you post, you can change the words, but not the sides: people have already picked them.
