After my suggestion to Patrice that having a comment feed field on each blog on list.blogug.ch, he (as usual) promptly added it. I have some plans using those feeds on the Planet, more about that later :)
Now it's your turn, go and add your comment feed there. And as most of the most use blogging tools in Switzerland do support comment feeds, that should get us a nice list (not sure if Blogger.com and the Sixapart people do support comment feeds out of the box, at least WordPress, Kaywa, Serendipity and Flux CMS do, didn't check the others)
