Elon Musk asks why Ethereum co-creator Vitalik Buterin left Twitter

Musk's question came as a reply to X account Autism Capital, who shared their opinion that "Vitalik needs to get back on X."

Buterin has been active on Farcaster, a crypto-centric Twitter-esque social media platform. "Farcaster feels like it's gotten to the point where it's quite usable as a Twitter alternative for lots of people," he wrote in February, adding: "The channels thing actually makes it *better* in many ways in my opinion."

Farcaster garnered significant attention last month. The launch of Frames — embeds that effectively turn Farcaster-based posts into interactive mini-apps — helped launch the platform's daily active users to new highs. This, in turn, saw an increase in revenue. It also shipped support for Solana addresses last month.

"Farcaster isn’t going to win the culture war," Autism Capital opined. "If he wants Ethereum to shine he should engage more on [X], not sequester himself with his chosen peers on an island. He will have far more impact if he engages the bigger community here."

Buterin has nearly 180,000 followers on Farcaster, where his account is tied to his Ethereum Name Service address, vitalik.eth. For comparison, he has 5.2 million followers on his X account — where he still posts, though somewhat infrequently.
