Yesterday, Google Apps launched an improvement that made dozens of exciting Google services available to Apps users for the first time. As part of this launch, Google Reader is now available to Apps users for free with their Apps accounts. For those Reader users who've a Apps account, if your admin has already transitioned your organization to new infrastructure, you can now use Reader by signing into Reader as normal with your existing Apps account.
Google Reader is a web-based content aggregator that allows you to pull updates from your favorite websites together in one place by subscribing to a site's RSS or Atom feed in Reader. It also makes it easy to share relevant articles with colleagues at your organization using Apps. Reader is integrated with your existing contacts list so address auto-complete works seamlessly.
And, those on the move, Reader also makes it easy and convenient to follow the stream of updates from your favorite websites on your mobile device, automatically synced through your Apps account.
Reader can be enabled by your domain admin[if not yet done] from Apps Control Panel at https://www.google.com/a/[your_domain.com] (replace [your_domain.com] with your actual domain name). If your organization isn't using Apps yet, you can learn more and sign up.
