While Facebook continues to grow, and some companies are getting more comfortable with using it for things like Pages, LinkedIn still fills the gap for users who want a more professional setting for social networking. A new service launching in public beta today at TechCrunch50 , Radiusly , wants to take the idea of Twitter and put it in more of a professional setting, as well. But unlike Facebook and LinkedIn which exist as two totally separate networks, Radiusly wants to integrate its service with Twitter. Users will be able to publish an update they leave on Radiusly to Twitter (and Facebook, as well). But the key selling-point is that in the Radiusly environment you can also do much more, such as have a professional profile, resume, sample works, and photos.
