I have a list of about 30 RSS feeds I would like to share with the world. I don't expect my audience to all be opml experts or willing to take an opml file and import it into their rss reader of choice. I do expect them to be able to follow a link in browser, but not much more.
Bloglines, it seems used to have a sharing feature like this, but it seems to require me to send an email to each person in the world who might want to see my list. I'd rather anyone with a browser be able to see the list or better yet, the posts represented by the feeds.
There used to be a service called share.opml.org which appears to redirect to an unreleated entity now. That would have answered my question if they hadn't shut down.
