I like those suggestions, especially “Over Exposed TV Personality” and additional forum ones like Best/Worst Prediction and Biggest Surprise/Disappointment.
I’d probably still keep in Best/Worst Journalist and maybe “Rising Star” in the TV news categories but aside from that, good job reducing my rather long list! 
The old awards had spots for us to vote for the best/worst in the media, so I personally think the revived version should too.
The Logies, AACTAs, ACRAs, Walkleys and a bunch of other media industry awards give out prizes related to the media highlights of the year, so Media Spy should too…even if media organisations & personalities are highly unlikely to add “Media Spy Awards Winner” to their CVs! 
Those are good suggestions too, even if @SydneyOnAirTV has probably already won “Mocker of the Year” by default!
