A group of researchers at France's CNRS public research body have developed an app to help users migrate from X to other platforms. The "HelloQuitX" campaign (a play on "Hello Kitty," since the letter Q sounds like K and X is pronounced "eeks" in French) allows users to transfer the lists of people they follow and their followers to Bluesky or Mastodon. The CNRS says it will delete personal information after migration. David Chavalarias, a mathematician at CNRS, says more than 5,000 people and organizations have signed up so far. Here's more from France 24.
