Bizarre content-free media column shared by everybody (8)
I believe the answer is:
communal
'shared by everybody' is the definition.
(belonging to everyone)
'bizarre content-free media column' is the wordplay.
'bizarre' indicates an anagram.
'content-free' says to hollow out the word (remove centre letters) (remove the inside letters or 'content' of the word).
'media' with its middle removed is 'ma'.
'ma'+'column'='macolumn'
'macolumn' is an anagram of 'COMMUNAL'.
(Other definitions for communal that I've seen before include "Involving sharing of work and property" , "Available to all locally" , "For a group of people" , "Shared by a group" , "Owned in common" .)
