Also inspired by "Hot Network Questions" randomizes too much when navigation in browser history and Websockets break caching.
I have the feeling that there is a limited number of question-groups that change upon each page-reload/history-navigation, with each group consisting of a fixed set of questions.
Would it be desirable to add navigation there (next / previous)?
At the moment, this could also serve as a quick-fix for the problems described in above mentioned questions.
