Facebook at Work is very different from LinkedIn. I doubt they will compete with each other at all - at least not any time soon.<p>LinkedIn is focused on helping companies find and recruit employees, and also helping job-seekers find new jobs. Facebook at Work seems to be focused more on communication and collaboration within a given company or project.<p>Of course, it&#x27;s entirely possible that Facebook at Work would grow into something closer to LinkedIn.  Despite LinkedIn having a huge head start in this area, Facebook probably could catch up. Lots of people already have Facebook accounts, and people generally like having fewer accounts for things rather than more. Plus, Facebook could easily replicate a lot of the recruiting features that companies currently pay LinkedIn thousands of dollars per year for.
