One of the best ways to get engagement on your intranet sites is to bring in a relevant Yammer community to SharePoint using Yammer Conversations. Instead of creating a destination to ask a question, this allows you to bring Yammer directly into your intranet and engage your users where they are.
But what about when you are in Yammer? The SharePoint site associated with a Yammer community is a team site that is independent from the communication sites on your intranet. You can bring Yammer into the intranet, but can you bring the intranet into Yammer?
