ibm pizzabox 326m

Replik auf … Die Rückkehr der Datenleichen. « Pflaumensaft

Wenn ein guter Vorschlag, wie der des Datenbriefs schlecht beschrieben wird, dann kommen Angstzustände, wie die von “Pflaumensaft” heraus. Dabei kann man ganz leicht aus dem Datenbriefkonzept die Absicht der Autoren herauslesen.
