For the first time I personally have seen today a Yammer related question on SP.SE and wondered if they were off-topic.
As they are not considered off-topic in general, would it be helpful to update the Help Center > Asking page regarding Yammer (similar to InfoPath related questions)?
We accept questions about the SharePoint platform. This is defined as the functionality within:
the SharePoint server range of products (i.e. SharePoint Foundation and Server, Windows SharePoint Services, SharePoint Portal Server)
SharePoint Designer
- InfoPath where it integrates with SharePoint
- Yammer where it integrates with SharePoint
