We should provide better informations about the following edge use cases of the TopStories feature:
If there are only a few (around 5) subscriptions, the feature will not get the expected results (story list looks like a list of duplicates)
If there are no stories (e.g. no feed update happened in the configured timespan - currently 7 days - it will not return any story, instead an empty page is displayed. This should not happen, at least we should display a message about "no stories found in the selected timespan" or similar.
