Yoono, a nifty browser plug-in and desktop application that serves as both a social network aggregator and media hub, is upgrading its offering today with YouTube integration, additional language support, and further Twitter functionality. Yoono aggregates and centralizes your online profiles, including IM tools like Windows Live Messenger, Google Talk and AIM as well as a wide variety of social networks such as Facebook, MySpace, Twitter, Flickr, and more. The app also includes real-time search capabilities powered by OneRiot.
The new YouTube integration allows you to see all of your YouTube updates (new videos, comments) in your stream; access your Channels (subscriptions, playlists, favorites, uploads); search YouTube videos; playlists and channels directly from Yoono; and share, favorite, comment on and even download videos directly from either the plugin or desktop application. And Yoono now allows you to favorite tweets and reply all from the application.
Via a crowdsourced translation project, Yoono now has versions in Spanish, German, Brazilian Portuguese, Swedish and Polish in addition to English and French. Yoono says that 22 additional languages are actively being worked on by the community.
Yoono, which has seen 4.5 million downloads, has also launched an alpha version of Yoono for Google Chrome, and is expecting the beta version of the browser plugin to hit the Chrome extensions gallery very soon. Given the popularity of Yoono on Firefox (the plugin is the most downloaded social networking add-on for Firefox), the extension should be popular among Chrome users. Yoono says that the next step is entering the mobile market with iPhone, iPad and Android apps in the works. And the startup plans to add more services to its hub, including Google Buzz, Foursquare, and Yammer.
