LinkedIn rolled out polls this week, a cool new feature for LinkedIn Groups (important distinction: this feature is not available for Company Pages). The feature has been rolling out over the past couple of days, and if you haven't seen it yet, you're sure to soon. LinkedIn has also let you like, comment on, and follow polls, helping spark discussion and increase user engagement with the group. Let's take a look at how to set up polls in LinkedIn Groups, and discuss 5 creative ways to use this new feature.
