Ok, just for fun this is what I did. I went back to all the contestants individual threads and looked at how many posts there were and if they were -, neutral or + and if the were trending in a direction. This is what I am predicting based on that information. Disclaimer: This is just one mans reading of everyones posts and analysis of that.
First out, of course was Ryan. 10 posts, mostly negetive.
Next out: Janet - 4 posts neutal to - "loner on the boards"
Daniel: started slightly - and went down from there. 34 posts, not good to put yourself out there.
Jenna: 40 posts: Only thing that kept her was the woman won immunity (hey, this is my analysis, let me have fun)
Dave: 34 posts: neutral to -, also very not UTR
Shawna: 9 posts: neutral to -, not a lot of support since Jenna went. Heidi was more adaptable and was kept around.
Joanna: 8 posts: Slightly -
Deena: 3 posts: Neutral: Not enough support to stay.
Rob: 21 Posts: Neutral: Gets caught in a lie and gets booted (by booted)
Roger: 11 posts: Mostly +: Too bossy
Heidi: 21 posts: Mostly +: Christy finds out she didn't relate to her and gets the guys to vote her out.
Alex: 6 posts: Mostly +: Getting tough now, all remaining were +
Christy: 18 posts: Mostly +: Kept one more round because she had more posts.
Butch: 11 posts: Neutral to +: Since he went up from neutral to + he stayed one more round.
Jeanne: 10 Posts: Just about ever post is positive, but
Matthew: 21 posts: Was able to overcome some negetivity in the beginning to turn positive in the end (and wins the final 2 immunity challenges) to take home the million.
Well, that is my "spoiler" analysis of the information from the board. All in fun...
