Mark Zuckerberg Takes Shots At Elon Musk's Twitter As Rival App, Threads, Debuts

Mark Zuckerberg apparently can't wait to get into an Octagon with Elon Musk to take shots at the billionaire ... he spent plenty of time Wednesday night throwing keyboard jabs at his nemesis -- as part of the rollout of his new app, Threads.

The Twitter rival made its debut right around dinner time ... and just a few minutes into its kickoff, Zuck took to the site -- which many are calling the "new Twitter" -- to go after Musk and his bird app.

First, Zuckerberg tossed shade at Twitter while explaining to Mark Cuban he hopes Threads is a more "friendly" area for people to interact.

"That's one reason why Twitter never succeeded as much as I think it should have," he wrote, "and we want to do it differently."

Later, the Meta founder told UFC fighter Mike Davis he's got hopes Threads will outgrow Twitter one day.

"It'll take some time," Zuckerberg said, "but I think there should be a public conversations app with 1 billion+ people on it. Twitter has had the opportunity to do this but hasn't nailed it. Hopefully we will."

There were some veiled comments from Zuck about a potential fight with Musk too ... while replying to new signups throughout the night, he consistently made references to winning "round one" of Threads. He also laughed at the prospects of the billionaire superfight being called "The Meta Threada." He spent a whole lot of time interacting with MMA stars like Jon Jones as well.

Zuck even appeared to get back on Twitter after an 11-year hiatus to get in another little ribbing at Musk ... with an account apparently associated with him tweeting out the Spider-Man meme.

No date has been set for the potential Zuck vs. Musk superfight -- there's a lot of hangups over the size discrepancy between the two -- but it's clear, the guys are more than content battling each other behind computer screens while it all gets sorted out.
