Alle Zahlen wurden ermittelt auf einem Newsserver mit redundanter Anbin-
dung fuer de.* unter Anwendung ueblicher Filtermassnahmen. Steuernach-
richten werden nicht erfasst; Postings, die supersedet oder gecancelt
wurden, bleiben erfasst, sofern sie das System ueberhaupt (und vor der
Loeschnachricht) erreicht haben. Crosspostings werden in jeder Gruppe,
in die sie gerichtet sind, gezaehlt, aber bei Ermittlung der Summe be-
reinigt; daher ist die Postinganzahl fuer de.* gesamt niedriger als die
Summe der Postinganzahlen der Einzelgruppen.
Die Daten stehen graphisch aufbereitet unter <http://usenet.dex.de/> zur
Verfuegung.
