Apparently Usenet is back, under new management, and actually doing something about the spam problem.

Nice to see.

Usenet, IRC, SMTP, FTP, Gopher -- these are the original protocols of the Internet, before the Web ate the universe. Things were better when they were dominant in their areas. We were outside corporate control, governments could barely be bothered to participate let alone police, we considered these things to be solved problems.
