In a blog entry, one gets put forward (5)
I believe the answer is:
posit
'put forward' is the definition.
(to posit an idea is to put it forward)
'in a blog entry one' is the wordplay.
'in' is an insertion indicator.
'a blog entry' becomes 'post' (a blog post).
'one' becomes 'I' (Roman numeral).
'post' placed around 'i' is 'POSIT'.
'gets' is the link.
(Other definitions for posit that I've seen before include "Assume something as a basis for discussion" , "state" , "Lay down as principle" , "Assume as a fact or principle" , "Suggest" .)
