Earlier this week Google made a significant change to Google Reader. You can now watch videos from dozens of sites without having to leave the reader. This means you can set up a RSS search feed, from say YouTube, and watch them all as a playlist in reader.
Page views? What page views? If no one is actually visiting your site, how do you monetize and sustain your business model? Creating meaningful social media metrics will be quite a challenge in this age of feeds, where content can be stripped of much of the branding, advertising or even authorship by a feed browser like Reader or Sage. I think it's about influence. At least, that's what some wiser blogging heads than I seem to believe.
Update: I subscribed to the most viewed feed from YouTube and then zipped over to Reader. Sure enough, the embedded Reader widget on my Google homepage now will pop up a window with a YouTube video embedded and playable within it. Cool.
