Twitter’s new CEO and owner Elon Musk is rattling the cage at his social network and ruffling a lot of feathers both inside and outside of the company. But while some in the tech world describe that kind of chaos as a garbage fire, others see it as something very different: an opportunity.

But as a first step to gathering interest for his New Twitter, Gabor has put together a sign-up list for people to register their interest as he works away. (Note: The name on the sign-up page, T2, appears to be an abbreviation for Twitter 2, but Gabor says this is just a placeholder name.)

Now you might be asking yourself, why pay attention to this? Isn’t Gabor getting a little ahead of himself here? He doesn’t have a name, or even a product, yet.

Well, yes. Gabor is in that sense just one of hundreds of millions of founders out in the world noodling on ideas. But there are a few things that set him and his alt-Twitter effort apart.

He’s worked on products at those two titans between and after those acquisitions, and that experience — he focused on Timeline, new-user onboarding and logged-out experiences at Twitter; and on many, many different consumer ideas as director at Area 120, Google’s in-house incubator project — has given him a taste of what’s interesting, and what is not. And also what works, and what does not.

“I had been thinking about a new Twitter for a while,” he said. “But after multiple friends of mine still at the company were laid off last week, I thought to myself, ‘This is the thing I’ve been thinking about for so long! Maybe this is the time.’”

Gabor is long on big-picture ideas at the moment.

“I want to build the next public square for discussion. I want it to be delightful and fun, rewarding and valuable, and safe from harassment,” he tells me. “We’ve had 15-20 years of content moderation experience on the internet now, and so let’s build that in.”

He’s even had some investor interest, which he has been building via iMessage. That inbox includes a former Twitter-exec-turned-investor who he will not name, who has already texted asking how much money Gabor would like to have to get this new bird off the ground.

And he’s had plenty of unsolicited advice. Twitter is great for that.

“Someone asked last week, why doesn’t someone just start a new Twitter? It would only take three days and $50 million,” he said. “That’s what got me first to ask what a roadmap might look like. I think for me it wouldn’t be a three-day build, but it also doesn’t take $50 million.”

This brings up many other questions… not least why he thinks he can build what Twitter has never managed to build itself, or why yet more centralized social media walled gardens have any future at all given all the problems we’ve seen in the ones we have today.

For now, his hunch is what he has: Creating something from scratch will be easier than trying to fix something that’s already big and in operation, and that it definitely won’t be as simple as just bringing together what he calls “the best people,” but also not impossible.

“I think right now I’m seeing this empty space,” he said, “and I want to be in that space.”
