Had an interesting request a few weeks ago. HR wanted to be able to share pages out to Yammer. I instantly ruled out a workflow because I couldn’t post as the user. Then ruled out a console app for 2 different reasons: the logic could get complicated and it didn’t allow for much flexibility. I went over to the Yammer Customer Network and started poking around. I ran across a few threads that talked about using the bookmarklet so I went and took a look at it: https://www.yammer.com/company/bookmarklet
<h2>Share this page . . . </h2>
The code will give you the share to yammer button:
Once the user clicks the icon a new window will open and – as long as they’re logged in to Yammer – they’ll be able to create a new Yam with the URL of the page they want to share in the update’s body.
Give it a shot and let me know what you think.
