Exposing the number of subscribers from large RSS readers is a nice addition, but it also slightly nudges one to centralization. I try to let site owners know I'm subscribed to their feed by adding an URL parameter like /?rss_ref=heyhomepage.com They might or might not see this RSS referrer in their own visitor statistics. I also do not consume all the article's content solely in my reader, but I show a short summary and then click the link to the article. This way I can enjoy their (personal) site and they can see my traffic more clearly.
