How do I navigate this olduse.net site? Is this a forum? I can't make heads or tails of how to see all those articles you mentioned. I've clicked every link on the homepage.
Use your Usenet client to connect the server nntp.olduse.net. While the original news client rn by Larry Wall written in 1984 is probably not working today, other implementation, such as slrn is still here.
Note that olduse.net is a playback of Usenet, time-shifted 20 years back, some of the events I mentioned has yet to occurs, you can navigate the website, download the original archives, and load it by your own to explore.
If you don't have the setup yet, to get an quick idea of how it works, read these interesting articles.
