It feels really cool to be a founding member (and first secretary) of something I really hope might do some good in the world: Kamratdataföreningen Konstellationen. In short, it's a Swedish non-profit association intended to promote and help provide free and open source software to the broader Swedish political left, and basically try to get organisations less dependent on things like Facebook and Twitter where they can be thrown out with little to no warning (which has happened in the past), and where people can be easily tracked.
So far, we've got a Mastodon instance and a Matrix chat running, and we're working on setting up a bunch of other services. In the long run, we're hoping to develop software to slot in where we find something is needed.
