Survivor right now

i am watching Survivor as we speak and i have two things to say so far (15 minutes in to it)

1: they just did the old drop-your-buffs-and-let-us-make-new-tribes thing. do you think they decide to do this at the beginning of the season, or after watching the tribes and seeing how it goes they then decide what could mess with people and throw off strategies the best? it was cool and a big twist the first time they did it, but now it is becoming a little to commonplace every season.

2: the one good thing that came out of it was it made lisi say something to the effect that she was hoping to go home and would have been happy had that been the case - her happy little world was thrown off kilter and she reacted without thinking. it was great! when will people learn to think before they speak on that show?

45 minutes later... speaking of keeping their big mouth shut: rocky was doing such a good job of that for the first few days and now.... not so much
