How to Run a Hashtag Chat on X: Step by Step

Search the hashtag before you announce it, and use CamelCase for readability.
Five or six questions fill an hour. Space them about ten minutes apart.
The Latest tab of the hashtag search is the chat room.

Hashtag chats were one of the things early Twitter did best: a regular hour where people with a shared interest met around a tag, answered the same questions and found each other. They still work on X, and with Communities gone they are one of the easiest ways to give a group a heartbeat.

1. Choose the hashtag

The tag is the chat's address, so treat it like a domain name.

Short. It goes in every post and eats into 280 characters. Aim for under 15 characters.
Specific. #DesignChat is probably taken. #TypeDesignHour might not be.
CamelCase. Capitalise each word: #TypeDesignHour, not #typedesignhour. Screen readers read the words separately, and everyone reads it faster.
No year unless it's a one-off event.

Then search it. Open the hashtag's Latest search and scroll back a few weeks. If it's in use for something else, pick another. The hashtag planner does these checks and gives you the search links.

2. Pick a time

Find out where your members are before you choose. A Thursday 7 pm in New York is midnight in London and the early hours of Friday morning in India. The planner shows each session in several time zones at once, so you can see who you are leaving out.

Regularity matters more than the perfect slot. Weekly is the classic rhythm; every other week or monthly works for smaller groups. Once you choose, stick with it so people can build it into their week.

3. Write the questions

Five or six questions fill an hour, about ten minutes each. Good chat questions:

are open, not yes/no
are short enough to fit, with "Q1: " and the hashtag, in 280 characters
move from easy (introductions) to deeper (problems, advice)
end with something forward-looking ("What will you try this week?")

Write them before the chat and schedule them. The planner formats each one, counts characters the way X does, and gives you a Post on X link.

4. Announce it

Post an announcement a few days before with the time, the tag and the format. Then post a reminder an hour before. Pin the announcement to your profile. If you've built a knot for the community, add the knot's share link so people can follow the members' feeds too.

5. Host the hour

Welcome post at the start: ask people to say hi and where they're joining from.
Questions on schedule: "Q1: … #YourTag". Participants reply "A1: … #YourTag".
Engage. Like and reply to answers, quote the good ones, introduce people to each other.
Wrap-up at the end: thank people and say when the next chat is.

Keep the hashtag's Latest search open in one tab and your notifications in another. It moves fast. Nobody reads everything, and that's fine.

6. Archive and follow up

The day after, share a date-bounded search as the archive:

#YourTag since:2026-11-12 until:2026-11-13

(until: is exclusive, so it's the day after the chat.) The planner produces one of these per session.

Then add the regulars to your community List. After a few weeks, the people who keep turning up are your community, and the List is how you keep them together between chats.

Questions

How long should a hashtag chat be?

An hour is the classic length. Thirty minutes works for a small group or a quick check-in.

Do participants need to follow each other?

No. Everyone follows the hashtag's Latest search, so they see every answer whether they follow the poster or not.

What happens if spammers jump on the hashtag?

Mute or block them and keep going. Choosing a specific tag, not a generic word, makes it far less attractive to spammers.
