I finally acquired a copy of all my Usenet posts for all time; such fun finding my first post! But the graph of my posting activity is sad:
Most posts are before summer 1994, when I graduated from college. Usenet was a hugely important thing for me, both a technical touchpoint as I was learning Unix and the Internet and a social touchpoint as I was coming out. Now mailing lists, the Web, and blogs have replaced Usenet as the primary online social medium. I miss the exclusive club we used to have.
