Gwene is an RSS (and Atom, etc) to Usenet News (i. e., NNTP) gateway.
If you wish to read various feeds, but don't want to use one of those new-fangled web browser thingies (they'll never take off), you can just point your Usenet news reader towards news.gwene.org and read all the kitteh blogs from the comfort of something I don't quite know how to end this run-on sentence.
Sign up single feeds or add all your feeds by uploading an OPML file.
Gwene is a sister site to Gmane, which provides a bidirectional mailing list to NNTP gateway and archive. As opposed to the Gmane site, there's not much of a web interface to the gwene.* newsgroups, but there's a site showing snippets from the articles.
The gwene.* groups will be fed out to any news servers that are interested in getting a feed, so that people can read these groups without talking to news.gwene.org directly, but I have to figure out how to set that up first.
The RSS to NNTP software is free software.
The person "responsible" for this is Lars Magne Ingebrigtsen, and I can be reached at larsi <at> gnus.org. If you have suggestions for Gwene or Gmane or how to increase the number of kitteh blogs in the world in general, I'd suggest posting them on the gmane.discuss newsgroup.
