I’ve compiled a list of all the radfem blogs I remember from some years ago and which are (largely) inactive now. Most of these people aren’t around the blogosphere anymore. However, you might still find some useful things in the archives.
Unfortunately, some of my favorite bloggers - polly, Sparkle*Matrix and Witchy Woo - have either deleted their blogs or password-protected them. And many more I would have listed are gone, too.
EDIT: I added some more blogs and will post this as a link under my tumblr profile.
