My first usenet post11 Jan 2005
My first Usenet post? 7 Aug 1994 in comp.os.linux.misc: "I visited the US last month, and though I didn't look very hard, I was disappointed to see nothing about Linux in any of the bookstores I
visited." (Prompted by Matthew's first Usenet post.)
Update: Ooops, just found an older one: 12 May 1994 in comp.text.tex: "Is there any way to convert (TeX) to a format that can be imported
into Quark XPress on the Macintosh?"
