Fun fact aside: Arno Schmidt's grandnephew is Dave Winer. We know Winer today more as the chief populariser of RSS but his life's idea is more in Outlining, organising your thoughts in nested lists and, since he's a programmer, coding in and on outline structures.

If I remember correctly from his blog Winer and Schmidt never had much contact, language barrier and such, so it's more of a coincidence.
