Recently, I've found Yammer and SharePoint to be a terrific mix for sharing information and small updates in my org.
First, I started by storing organizational information in static SharePoint pages.
Next, I use a public Yammer community to post about an updates to the content on the page. The Yammer posts are embedded to the page by topic.
What's neat about this setup is that it can be completely opt-in. Staff that are interested in these updates can subscribe to the Yammer community or the individual topic if/when they choose.
Of course, don't forget to mute your community to prevent "Discovery" emails from being sent to anyone that isn't subscribed.
This is a simple use-case, but I hope you find it helpful!
