Maybe I'm not that good, but would love to find a remote job paying 3-4k...
In my circle of friends who do usually work remote, there are a few that want to move to more rural areas. The number one concern is availability of broadband, which is just terrible in Germany. Further down is friends/family not being close and possibly sticking out very much. I don't think remoteness is an actual issue (because there really isn't remoteness anywhere in Germany, it's very densely populated, and saving a lot on rent & co might well offset the cost for a few hours of driving every other weekend to meet friends.
You also don't have to go rural, there are plenty of mid sized towns with cheap housing prices (and often a university and/or other cultural institutes, like Halle or Cottbus).
My main concern is that while we don't really standout in Berlin, in a smaller town we will be considered more "exotic" & especially for our kids I'm afraid it will translate to mobbing in school.
I do realise that this only applies to those who CAN work remotely but that seems to be a large chunk of the userbase for HN.
