The new extension makes it possible to add new subscriptions and see the unread count
The demise of Google Reader provided a clean slate, making it possible for other news readers to flourish. Feedly has positioned itself as a strong contender, but there are many others. Digg entered the battle with Reader.Digg Reader was rather bare bones when it launched, but it's been getting better. Digg has now released a Chrome extension for Reader, making it possible to stay up to date without actually having to keep the website open in a tab.
The extension provides a quick way to see how many unread items you have. It also makes it easy to subscribe to the site you're currently visiting. Finally, the extension works as a shortcut to the Reader site.
It's nothing fancy, quite the opposite, but it doesn't have to be. It's a useful extension that complements the existing Digg Reader. Digg could have built a full-blown Chrome app, but it probably wouldn't have made it any more useful.
