In the IndieWebCamp community we try to do this also but even without RSS feeds if you don't want one. See my notes which have an h-feed site which is just the HTML marked up with Microformats so I don't need a special xml-feed. (I do have one for legacy reasons) And we use Webmentions (it's like Pingback) to ping others about us mentioning them. I also show their mentions under my own posts.
