It's a bit of a shame, Ted being so unpopular (5)
I believe the answer is:
hated
'unpopular' is the definition.
(I've seen this before)
'it's a bit of a shame ted being' is the wordplay.
'it's a bit of a shame ted' becomes 'ha' (I can't justify this - if you can you should give a lot more credence to this answer).
'being' becomes 'Ted' (Ted is an example).
'ha'+'ted'='HATED'
'so' is the link.
Can you help me to learn more?
(Other definitions for hated that I've seen before include "viewed with hostility" , "was unable to stand" , "Despised" , "Detested" , "gave stinking review to?" .)
