Google Reader Tracks Personal Attention Metadata
Googlified says the Google RSS Reader has added a feature that shows just where your attention goes. Reading trends displays the items you read, starred, shared in the past 30 days. Subscription trends identifies the blogs that update the most and which blogs are inactive. More on the Google Reader blog.
Neat idea. It's a bit scary to see just how much time I spend with RSS feeds. I would love to see them open this up on an opt-in basis so we can see aggregate data from all users. Google can take this and turn it into a Share Your OPML on steroids without any intervention from the user.
Now imagine if they were turn this information around and sell it to marketers. Thankfully, I bet their privacy policy prohibits it. Still, it's an interesting idea if Google can pull it off in an ethical way and on a completely opt-in basis. Tie this with Adsense for Feeds and you have an interesting platform.
