Gmane [via Play With the Machine] pipes mailing lists into newsgroups, where they're also archived (the gateway works from news to list, too). There's also Genecast, which pipes RSS feeds to newsgroups (intriguingly, this News Service is the first in "a series of products that establish your presence on the web, and keep you informed about someone else's"). Nice to see Usenet innovation again. Good to see the experience and work in building news readers (which are everywhere, command-line to mail client, and often using the same good code as developed to read and write mail) not going to waste.
