Google: Reader Trends

I wonder if it's an experiment, but I was offered a trend view of my aggregator reader habits in Google Reader. Things presented:

• Active and inactive feeds by items per day.

• Reading, starring, and sharing activity on a per feed basis
• A tag cloud, generated from your tagged feeds, highlighting tags by items appearing (size) and items read (shade).

Kewl!! One of the nice things about this personalized view, is that it becomes quite easy to prune inactive feeds. A small win in the fight against information overload, but a win nonetheless. Now if they'd only provide some per blogroll search capabilities.
