How I miss the intensity and the wit of the microblogging blitz that flooded our timelines during each ICA annual conference back in the golden age of Twitter. I'm very disappointed that our community, of all academic communities, didn't find a new home to save and cultivate all that jaunty energy. We're now scattered between Mastodon, BlueSky, and despair.

Action speaks louder than words.

Danish Minister of Digitalisation Caroline Stage wants to phase out Microsoft from the ministry to reduce the dependency on US tech.

This will be a long process. But actual action, not just talking points, is noteworthy!

H/t @pernillet for pointing to this.

Is #AI messing with our #democracy? In his #WIConf25 keynote @claesdevreese looks at the evidence from elections in 2024. It‘s part of the campaign toolkit rather than a magic wand.
