Google is planning to unveil a broad new social product on Tuesday that will integrate with at least two existing Google products. Some details emerged earlier today on the Wall Street Journal (“a new feature that makes it easier and faster for users of Gmail to view media and status updates”), but our understanding is that the product goes well beyond a Gmail integration. As I wrote last night , there is still a lot of room for improvement in online social services.

Last year, Box.net acquired a small company called Increo without giving much insight as to what they’d be doing with the technology. Today, we’re seeing the fruits of that acquisition: Box.net is launching a new integrated Flash file viewer, allowing users to immediately view over 20 file types from their browser, including most common document formats, images (including Photoshop), audio, and video. From a technology standpoint, Box’s new viewer has a lot in common with the converters you’ll find on Scribd and DocStoc: it takes documents and makes them readable in a Flash-based viewer, so you don’t have to worry about installing any extra software to view the file.

Boxee fans, today’s your lucky day: the service has just released its Beta to the general public. You can download the new version of the steaming video hub here .
