Working with online media's awfully superficial (3-11)
I believe the answer is:
one-dimensional
'superficial' is the definition.
(I've seen this before)
'working with online media's awfully' is the wordplay.
'working' becomes 'on' (e.g. a machine is working or on).
'with' says to put letters next to each other.
'awfully' indicates anagramming the letters.
'online'+'medias'='onlinemedias'
'onlinemedias' is an anagram of 'edimensional'.
'on'+'edimensional'='ONE-DIMENSIONAL'
(Other definitions for one-dimensional that I've seen before include "Superficial" , "Lacking in depth" , "Unsophisticated" .)
