The uselessness comes from the generational differences in what is useful and familiar.
So how about a discussion with journalism students about what they see as useless and what we older folks see as comfortable? (And granted there may even be some old-timers not comfortable with the fax.)
And remember that there is always the Beloit College Mindset List to see how today's students perceptions of the world are different from the profs. (And I am told by the authors of this list that it will be available in an expanded book form in time for the 2009 Fall term. Maybe the feature writing profs should look at this.)
