For example, in my set of subscriptions, even though I'm reading the majority of items in the evening, new posts seem to arrive in the middle of the day.
We also wanted to expose more fine-grained data. While it's useful to know what your overall reading trends are, we thought it might be interesting to also display this data on a subscription by subscription level. If you've ever been curious about when your favorite subscriptions were publishing new posts or when you were reading them, click the "show details" link in the upper right corner of the viewer. It's a good way to peak into your personal habits as well as the posting schedule of your favorite blogs. While you're in there, check out the other details - we also display the last crawl time and any errors encountered during that crawl. [Google Reader Blog]
