The keynote speaker who let the chat run the room
Six months ago, a conference organiser in Manchester messaged us at 11 p.m. on a Thursday. She'd just finished a keynote using Feedr, and the comments were still coming. Not trickling. Coming. Her speaker, a fairly well-known voice in tech ethics, had stopped talking for the last ten minutes and was reading aloud from the live comment stream instead.
The moment everything shifted
What struck me about that message wasn't that the speaker had improvised. It was that the audience had let him. Over 280 people in that room had their phones out, and instead of scrolling Twitter or checking email, they were typing. Upvoting comments. Reacting. The speaker would read a comment, pause, nod, and answer it directly. Then another. Then another.
The organiser wrote: "He was supposed to finish at 16:15. He went until 16:47. Nobody left."
This wasn't a failure of planning. It was a moment where the boundary between speaker and audience simply dissolved. I'd founded MRVL because I believed real engagement meant giving people a voice, not just a seat. But I hadn't anticipated that some speakers would be bold enough to actually use it.
Why QR codes beat friction
Before Feedr, running an interactive session meant either asking people to download something (nobody does), sign up beforehand (barriers everywhere), or use a platform that required accounts and logins. The friction was real. And so most speakers didn't bother. They gave their talk, took a few hands raised at the end, and moved on.
We built Feedr around one idea: make it invisible. Audience scans a QR code from the slide or printed agenda. Browser opens. They're live in seconds. No account. No app. Just a comment field and the rest of the room's thoughts. The speaker runs everything from their phone, iPad, or Android device. They see the live stream, the upvoted comments, the emoji reactions. They decide what gets seen, what gets replied to, what gets pinned so everyone can see it mattered.
That Manchester speaker didn't have a strategy going in. He just started reading the comments because he could see them. And the room noticed he was actually listening.
The moderation problem nobody talks about
Here's what we learned fast: open comment streams can turn ugly quickly. We had a church pastor use Feedr for a Sunday service and get hit with spam. A university lecturer had a comment section that turned into a argument. A podcast host couldn't keep up with the volume.
That's when we built the moderation queue. It sits on the Creator tier and higher. Comments arrive in a queue before they go live. The host reads them, decides yes or no, and only the ones that matter hit the stream. It sounds simple, but it changes everything. Suddenly a speaker can take questions from 500 people without losing control. The conversation stays constructive because someone is actually filtering it.
The emoji reactions feature came later, from the same insight. Sometimes people don't want to type a full comment. They just want to say "yes" or "interesting" or "deeply disagree." One emoji reaction takes a second. It's noise-free engagement.
When pinning becomes part of the story
I got another message last month from a conference speaker who'd used Feedr at a panel discussion. Three panellists, one moderator, and the audience posting questions. Normally a panel is just the three people talking at you. But this time, when someone posted a brilliant question that the panellists hadn't expected, the moderator pinned it. Suddenly it stayed at the top of the stream for everyone to see, highlighted, anchoring the next ten minutes of conversation.
That's a small feature. Pinning. But it's also control. It's curation. It says: this comment matters to where we're going next. Not all comments are equal. The best ones, the ones that shift the conversation, they float to the top.
We've seen speakers use this in different ways. One charity director pins comments that show real impact stories from the audience. A lecturer pins questions that reveal where the room's confusion is. It's not the same as a moderator filtering junk. It's the speaker or host saying: pay attention to this.
The analytics nobody expected to want
On the Pro tier, we built an analytics dashboard. Most of our users ignore it. But some don't. A corporate trainer wanted to see which comments got the most upvotes across all her sessions. A speaker working on a book wanted to understand which topics sparked the most engagement so he knew what to write about. A church wanted to see how many people engaged across multiple services to track growth.
The dashboard isn't fancy. It's just numbers: comments, reactions, top comments by upvotes, attendee count, session length. But it tells a story about what actually landed in the room. Not what you think landed. What actually did.
I mention this because it matters to the full picture. Some creators just want real-time interaction. Others want to build something from it. The data sits there if you need it. If you don't, you don't even open the dashboard.
What we learned from that Manchester moment
That keynote speaker changed something for me. Not the product. We didn't adjust Feedr after his session. But my understanding of what engagement actually is did shift. It's not the speaker performing brilliantly while the audience watches. It's the opposite. It's the speaker noticing the room, really noticing, and letting that change the direction.
Most people think interactivity means the host asking pre-planned questions. Feedr doesn't work that way. The host asks no questions at all. The room asks everything. The host decides whether to follow or stay the course. That's real control, and strangely, it takes more confidence than giving a rehearsed talk.
We've had lecturers use it once, on day one, and then build it into every session. We've had church pastors run it every week. We've had conference speakers become evangelists because they saw their rooms actually engage. None of them are using Feedr to scale like a webinar. They're using it to listen.
The Manchester organiser sent one more message months later. She'd booked that speaker again for next year's conference, specifically because of how the audience reacted. She wrote: "He gave the same talk but with the room driving it." Does that distinction matter to you when you're planning an event?
