Hi Sven, as Steven says, this feature has nothing to do with social networking. It's about gathering quick feedback from new editors about where they're experiencing trouble. We've announced this on the English Wikipedia here, where there's also a bit more discussion.
This is also an experimental test deployment. We generally try to set user expectations for a feature and communicate about it commensurate with the scale of deployment. For this first test, we're simply making a determination about whether the signal/noise ratio justifies additional development effort or not.
