"A video claiming to be from a Google team has surfaced on a public Google video page.  Hailing from the Reactor team, which works on the back-end for Google Reader, the video, which has since been removed, throws out some interesting blurbs on Google.\nSome of these blurbs say that Google Reader has two kinds of feeds: those that have only one subscriber, and those that have multiple subscribers.  Two-thirds of these feeds fall under the one-subscriber header, and are only updated once every three hours, while multiple-subscriber feeds are updated every hour.  Google Reader also uses 10 TB for storing the raw data, crawls 8 million feeds, and keeps the history of these feeds in its entirety.  Other information provided by this now-lost video indicate that more social networking options are planned for the future of these feeds, and many Google Apps use Google Reader's infrastructure for feeds.  In terms of monetization, other incentivization is planned for this towards publishers as well.\nSee here  for a deeper discussion of each point brought up in the video.  This is the second time in recent weeks that a video has been supposedly leaked from Google.  Remember the Googley Blues?\n\n\n\n"^^<http://www.w3.org/2001/XMLSchema#string>
