I never liked Benjamin. I hated that he won and he's produced some weird tweets. The one about wanting to see Jade and Maddie burn to death in a fire springs to mind. I mean fair enough if you don't like someone but wishing that on people (especially people you don't even know) is a bit extreme.
Re only Tim and Ben going to the Logies...I guess it makes sense since they're the only two that are still regularly on TV (especially at 9). Tahan did a Getaway special but hasn't done anything since, Jade works for 9 but it's behind the scenes, and I'm starting to think that they've stopped using Tully considering she hasn't been on Mornings in ages and Jade's been doing the Today Show jeep stuff instead. None of the others seem to have much or any connection any more. So I suppose Tim and Ben make sense since they're still actually on television (doesn't hurt that they were two of BB's faves either).
