I’d actually love to see something like this happen, as it seems to be something European governments and officials are embracing.

I had the chance to ask the responsible person of the EU commission about this at the last CCC congress and sadly he was much less optimistic. The answer basically boilded down to: as long as someone else funds and maintains it they are willing to put an intern or similar at work to post updates, but currently all these efforts are time limited and when funding for the 3rd party to operate them runs out, these efforts are likely to die off quickly. The actual buy in and willingness to operate their own social media infrastructure seems to be very low.
