I actually have no problem with "floaters," whether it's a strategy or just something a player falls into. Alliances aren't the only way to play the game. They crumble all the time. A person who can quietly stay under the radar during eviction after eviction is still playing the game. Victoria has shown that she's not a threat by not winning comps. She's been on the block a few times, but no one seems to be overly-concerned about voting her out. I don't think she meant this to be her strategy, but it's working because she's still there and several other people are not. The main goal of the game is to stay in the house. Whether a person does that through an alliance, being clueless, lying, backstabbing, turning on their friends, etc., it's the nature of the game. The person left standing wins. Of course you'll get more votes if you play with some degree of integrity and don't annoy the crud out of people. But if being a "floater" keeps you around, it's not necessarily a bad thing.
