After reading considerable Web discussion of my complaint to LiveJournal, I've come to the conclusion that LiveJournal was and is well within its rights to syndicate my weblog. They're using RSS as it was intended.
I also realize that I was wrong about not wanting my blog syndicated on LiveJournal -- or anywhere else for that matter. Syndicate away! I want this blog read widely! On LiveJournal and elsewhere! Just please abide by the terms of my Creative Commons license.
