I once asked about the use of "newbie" in forum subjects rather than 'rookie' or 'beginner' or 'novice' or some such.
I've lost my thread but I found an answer. The word "newbie" entered entered discussion groups back in the prime days of Usenet, about 1994 or so. The word 'newbie' was apparently computer technology slang from 1970 and is believed to be patterned after 'freebie' which was already a well established word in promotional materials.
