The browsers are one-by-one removing information about feeds from the user interface, so it's become harder for people to find your feed.
It just struck me as I was looking for the feed on the Rootstrikers site. I started to do a View Source and realized that of course most people wouldn't think to do that, or necessarily know how to find the feed in the source.
Update. I added the RSS Subscription Extension for Chrome, from Google, and it found a feed for the Rootstrikers site.
While I was at it, I added a feature to River2 that allows it to hook into Chrome's subscription extension.
