As a fellow user, overwhelmed to see the Beeb experimenting outside of Twitter/X!

The Mastodon experiment is extended for another half year.

There's an interesting footnote regarding BBC News making the switch to the platform (there are currently bots that mirror their Twitter content over there, but no official accounts):

We have been asked by a number of people on Mastodon to include BBC News social accounts in the trial. Because of the potential sensitivity around news stories, we need to be particularly careful with our editorial processes and within the scope of this trial we are not in a position to guarantee time and effort from other teams outside of R&D. This means we haven't been able to include BBC News in the trial yet, but we are working on it.

Would be interesting to see that becoming reality!
