LinkedIn, a professional business-related networking site, allows companies to create professional profiles for themselves as well as their business to network and meet others. Through the use of widgets, members can promote their various social networking activities, such as Twitter stream or blog entries of their product pages, onto their LinkedIn profile page.

Additionally, companies have voiced a preference for the amount of information that can be gleaned from a LinkedIn profile, versus a limited email.
