From the page: "Google is sitting on a goldmine of data around RSS feed reading and consumption. As most universally accept that Google Reader is the most popular feed reader, Google likely has a plurality of information showing when bloggers post, when people read, and what the most popular feeds, items, etc. are. So far, despite having all this detail, the Google Reader team has been largely reticent to reveal their knowledge, choosing instead to promote RSS as a standard, rather than setting bloggers up with yet more ways to measure one another."
