European here. Germans just think their beer is the best in the world and if you’re not doing it like them, you’re not doing it right.
Don’t get me wrong, the standards Germans apply to their beer production means that it’s rare to get a terrible beer there, but IMO it’s also not that innovative and the range of styles is fairly limited. There is a ton of choice in the US both in terms of breweries and styles. The variation means you get more duds but also more excellent beers.
I suspect the large majority of people who use the Fediverse don’t want to be publicly trackable in this way. It would be fine for me if the people who did stayed on Facebook. To me, it’s not a goal that 100% (or any %) of Facebook users move to the Fediverse. What is important is just that the Fediverse has a critical mass of activity that it doesn’t completely die.
Also, maybe it’s just me (I’d be interested to hear what others think) but I think trying to track down old school or college friends is really something people only want to do for a few years. By the time I hit my mid 20s I didn’t really care anymore. There are people from school I sometimes think about and wonder where they are now, but ultimately, if I never tracked them down and they never tracked me down in the years since, the connection was clearly not that important.
