FaceBook, Twitter, LinkedIn and the new Google Buzz may be the biggest but they’re not the only fish in the sea when it comes to social networking sites, especially for small businesses.

Jonathan Blum of TheStreet.com recommends three free social networking applications for small businesses that are more streamlined than the Web behemoths.

XMarks: Download the application, open a free account, and you can store and share bookmarks about a client or job as a Web page, RSS feed or e-mail that will be available on any computer, allowing you to more easily share information with colleagues.

Jing: A Web collaboration tool specifically for videos and stills. Lets you store video, images or animations on the Jing server, which creates a Web link that can be sent via e-mail, chat or Web page. The bandwidth is not as strong as video sharing tools like Skype but it is simpler to use, says Blum.

Notepub: An alternative to Google documents, Notepub is a document collaboration tool that allows users to create and share simple notes on any computer. While you won’t have access to features like RSS or chat software, Blum says Notepub is a quick, easy way to share documents, images and files.
