This is what adds a lot to the social feel of SM, everyone can see who follows who.
This social feel is part of the reason why non-tech folks use SM over traditional Blogs to post online. If the goal is to move people back on to the more traditional web, then it is necessary to create this social feel.
Now, the anonomity of RSS also has advantages, but similar to how the OP added "Webrings" to RSS, social proof could be added to RSS with another tool. So that all subscriptions can remain anonymous if wanted, while still providing the social feel.
Disqus is a little bit like that for comments. Disqus is also proof of concept for the OP that such "organic" additions to the standard blog concept.
