The No. 1 social networking website Facebook recently added one more mobile technology to its arsenal with the acquisition of Spool, a startup specializing in bookmarking and sharing content on smartphones or tablets.

"The Spool team has deep expertise in mobile software development and a passion for making content easy to consume," reported AFP.

Financial terms of the acquisition were not disclosed.

Spool lets users organize online content using bookmarks so they could access digital stories, videos or other material at their leisure or on different Internet-linked gadgets.

"We started Spool to make content easy to consume on a mobile device," the startup said in a blog post telling users the service was closed and the team joining the world's leading social network. "We firmly believe that solving these problems will be increasingly important as the world accesses the Internet primarily through mobile devices."

Facebook, which has its headquarters in Menlo Park, California has made a priority of improving its mobile offerings to keep in synch with users who are increasingly accessing the service from smartphones or tablets.

Spool currently has five employees and all of them are moving to work for the social-networking giant. Additional details of the acquisition were not disclosed, but this appears to be mainly a talent acquisition; Facebook will not be getting the technology behind the service, or its user data.
