RSS-Feeds: Hype or Trend

Since I heard from RSS a few years ago I use this technology excessively. Started with a Feed Reader Software I switched a year ago to Google Reader, because I found it good, to have the collected feeds available all over the world (in MY world --> at home and in Office). Today I was looking in my Usage-Trends (how many feeds do I have subscribed, how many articles have been read, how many articles have been marked, ...) and found a tab, called "Most Obscure" subscriptions. Looking at the Facts, posted on this tab I was shocked. Most feeds where only subscribed by a handfull of people. For Example the RSS-Feed of the Austrian Automobile Club (ÖAMTC), which shows up the traffic-warnings for Austria (here) is only subscribed 44 Times ! Mediamarkt, a famous Electronic-Shop has only 1 Subscriber ! (which is me). OK, these facts only contain the feeds, subscribed by google-reader (here), but I thought, the amount of subscribers was a lot higher than this ...
