Some days ago, the ones responsible told me, that this is an experiment. They want to try it out, and see where it goes. There are no explicit goals, but they will track, how many visitors will come to their site through the links posted here.
They'll also keep the other instance https://dev.ard.social, where they will test and develop stuff. They want to contribute to #Mastodon and the #Fediverse. Code will be published on the GitHub-Account of the #NDR: https://github.com/NorddeutscherRundfunk
(2/4)
They are promoting the account on other #SocialMedia ("even on #Twitter" – heavily with multiple Tweets right now), something the @ZDF didn't do as much:

It was just some days ago, that the @ARD made public, that it wants to get rid of hundreds of its accounts, mainly on Twitter. They want to focus on the ones with a big following and also "keep an eye" on Twitter under #ElonMusk
