How to moderate a live Q&A session: roles, columns and on-air rules

Richard Frantzen, founder of AskTide · Updated 2026-11-04

Knowing how to moderate a Q&A session well is most of what makes a live Q&A feel sharp instead of chaotic. This guide gives you the roles, a four-column workflow, rules for filtering and rewriting questions, and a checklist you can print and take into the control room.

Short answer: To moderate a live Q&A session, split the work into three roles (host, moderator, graphics operator), move every question through four stages (New, Selected, On Air, Done), and only shortlist questions that are on topic, answerable and short enough to read on screen. Rewrite long questions to about 100–140 characters for a lower third, merge duplicates, and keep two or three questions ready ahead of the host.

The three roles in a moderated Q&A

A moderated Q&A works when everyone knows who decides what. The host talks to the audience and the guests. The moderator reads every incoming question and decides what is worth asking. The graphics operator (often the producer or vision mixer) decides when a question appears on screen and when it comes off.

In a small production one person can be moderator and graphics operator at once. What you should avoid is the host moderating from a phone while also hosting: they will miss questions, and the audience will see them reading.

Agree before the show who has the final say. In most productions it is the producer: the moderator proposes, the producer disposes.

A Q&A producer workflow: New → Selected → On Air → Done

Whatever tool you use, think of the queue as four columns. Every question lives in exactly one of them, and everyone in the team can see where it is. In AskTide these are real columns you drag questions between, and you can add custom columns such as 'Follow up later' or 'Not used'.

Rule of thumb: the moderator owns New and Selected, the graphics operator owns On Air, and whoever takes a question off air moves it to Done.

• New: everything the audience sends lands here. Nothing in New is visible to viewers. The moderator's job is to empty this column, not to answer it.
• Selected: the shortlist. Questions here are cleaned up, rewritten and in the order the host should take them. Keep two or three ready at all times.
• On Air: the one question on screen right now. In AskTide only one question can be on air at a time; putting the next one on air sends the previous one back to Selected.
• Done: answered questions. Move each one here as soon as the answer ends, so nobody puts it on air twice.

This separation is what pre-moderation means in practice: the audience never sees a question that nobody has read. AskTide has no audience upvoting, by design, so the order of the shortlist is an editorial decision rather than a popularity contest. If you want the audience to vote on questions, tools like Slido and Mentimeter offer upvoting (checked November 2026).

Before the session

1. Write the rules down. One sentence each: what topics are in scope, whether names are shown on screen, how you treat abuse, and who has the final say. Share it with the host and the moderator.
2. Brief the host and guests. Tell them questions will be shortened for screen, that the host reads the on-screen version, and that guests can decline a question. Agree a signal for 'skip this one'.
3. Set up the session and outputs. Create the session, add the display output as a 1920×1080 browser source in your switcher, and pick a layout. See the OBS guide, the vMix guide or the TriCaster guide.
4. Give the moderator their own access. In AskTide, open the Share menu and use 'Copy link and password' for the moderator link. The moderator sees only the questions: they can edit, shortlist, move and put questions on air, but they cannot change settings, outputs or other tabs.
5. Seed the shortlist. Add two or three of your own questions manually, so the first minute of Q&A never starts in silence while the audience is still typing.
6. Rehearse one question end to end. Send a test question from a phone, move it to Selected, put it on air, check the graphic on program output, then move it to Done. Move test questions to Done (or a 'Not used' column) before doors open.

How to filter audience questions

Filtering is not about protecting the guest from hard questions. It is about choosing questions the audience will learn something from. Ask four things about every question in New:

• Is it on topic? If not, park it in a custom column for later or answer it in a follow-up.
• Can this guest answer it? A great question for the wrong person wastes two minutes.
• Is it new? If it repeats something already answered, move it to Done or merge it.
• Is it fair? A tough question asked in good faith goes in. A personal attack does not.

Aim for variety in the shortlist: mix topics, mix critical and curious, and do not take three questions in a row from the same angle.

How to group duplicate questions

In any Q&A with more than a few hundred viewers, the same question arrives in five different wordings. Pick the clearest one, edit it so it covers the shared point, and move the others to Done (or to a 'Duplicates' column if you want to keep count). If you show names, credit the person whose version you kept, or remove the name and let the host say 'several of you asked'.

AskTide does not merge questions automatically, so grouping is a manual, editorial step. That is usually what you want: a moderator can see that 'when does the bus route change?' and 'why is line 3 cut?' are really the same question, which a keyword match would not.

Rewriting long questions for the screen

Viewers read a lower third in the few seconds the host takes to read it aloud. Long questions either get a tiny font or wrap into four lines that cover the speaker. Rewrite instead: keep the question mark, cut the preamble, keep the asker's own key words.

Example. Original (230 characters): 'Hi, thanks for a great talk, I work in a small municipality and we have tried livestreaming our council meetings but almost nobody watches, so my question is what is the single most important thing we could do to get more viewers?' On-screen version (78 characters): 'What is the single most important thing a small council can do to get viewers?'

These are starting points, not limits: the real number depends on the width, font and font size you choose. AskTide's graphic editor has a live preview, so paste your longest likely question into it before the show and adjust width and font size until two lines look right. Always edit the text, never the meaning: if you shorten a critical question, it must still be critical.

Question types and what to do with them

AskTide has no automatic profanity filter. That is the point of a pre-moderated queue: nothing reaches the screen until a person puts it there.

Moderating questions during a livestream: timing

Plan around 2–3 minutes per question including the answer. A 30-minute Q&A therefore fits roughly 10–12 questions, and a 15-minute segment about 5–6. Tell the host the number at the start so they can pace themselves.

Put a question on air when the host starts reading it, not before: a graphic that appears while the previous answer is still running steals attention. Take it off (or replace it with the next one) once the answer is under way, so the speaker gets the full frame. Five minutes before the end, tell the host 'two more', and pick the strongest remaining question as the last one.

Stream delay matters too. Online viewers may be 5–30 seconds behind the room, so the flow of new questions lags what is being said. Do not rush to discard a question as 'already answered' if it arrived within half a minute of the answer. The hybrid event Q&A guide covers latency in more detail.

After the session

• Move the last on-air question to Done and take the graphic off program.
• Go through New and the 'Follow up later' column and decide which questions get a written answer.
• Export the questions to Excel from the questions toolbar in the manage view (the download icon) before you archive the session, so unanswered ones can be followed up.
• Debrief for ten minutes: which questions worked, which rewrites the host stumbled on, what to change in the rules.

A moderator link that only shows questions

The most common moderation accident is a moderator clicking the wrong thing: a theme change, a deleted output, a poll pushed live. AskTide's moderator link (/moderate/SESSION-ID, protected by a password) removes that risk because the moderator sees only the questions. They can still put a question on air, so in a one-person setup they can run the whole Q&A from that view, while the producer keeps the full manage view.

Frequently asked questions

How do I moderate a Q&A session online?

Collect questions in a pre-moderated queue, have one person (not the host) read every incoming question, shortlist and rewrite the best ones, and let the producer put one question at a time on screen. Move answered questions to Done so they are not repeated.

What does a Q&A moderator do?

A Q&A moderator reads all incoming questions, filters out off-topic, duplicate and abusive ones, rewrites long questions so they fit on screen, and keeps an ordered shortlist ready for the host. They also pass technical complaints to the stream team.

How long should a question be on screen?

For a lower third at 1080p, aim for about 100–140 characters, which is two lines at a typical 40–48 px font. Full-screen graphics can take more, but shorter is almost always easier to read while someone is talking.

How do I handle hostile questions in a live Q&A?

Separate tone from substance. If there is a legitimate point, rewrite out the insults, keep the criticism and warn the producer before it goes on air. Abusive or personal attacks never go on screen and are not read aloud.

Can a moderator put questions on air without access to the rest of the show?

Yes, in AskTide. The password-protected moderator link shows only the questions; the moderator can edit, shortlist, move and put questions on air, but cannot change settings, outputs or other tabs.

Can the audience upvote questions in AskTide?

No. AskTide has no audience upvoting by design: a moderator or producer decides what goes on air. If you need voting on questions, Slido, Mentimeter and several other tools offer it.
