Social Learning in business

I have really been focusing a lot lately on the benefits and negatives to social learning in the school and university platform. One section I haven't focused on yet is social learning in business settings. Business do this just as much as everyone else. Companies like Google like to create intranets in their headquarters that connect all employees from all sections on the company so they can collaborate and share ideas with each other. This is very positive because it can give different perspectives from all different people to get to the best possible solution. This system Google put in place is one of those things that you never knew you needed until you saw Google created it. Now however it is one of those things you could never live without.
