Hi,
As you might know, the 'Related Content on SCN' is a widget on the overview page of a space.
This widget displays blogs from any space that have specific tags
So if a blog was posted on one space but is relevant also for another space, by using the relevant tags it will displayed on the relevant spaces in the widget.
This Blog can be used as an example:
This blog is published on support space.
it is taged with "eam"
Therefor it will be displayed in the "related Content on SCN" widget on the following space Enterprise Asset Management (SAP EAM)
This widget was not working for several weeks and it is back now.
