All of these spoilers are questionable.

The "Kathy goes on April 11th" spoiler comes from the EZ board, where a poster (who is trusted I think) from Vermont talked with a friend of Kathy's (who is also in Real Estate) who gave him this info. This friend said she didn't watch or care about Survivor, which I think is suspicious--if she really is good friends with Kathy I'd think she'd be pretty interested in this Survivor, regardless of how she felt about the show before. I don't see this as having any conclusive evidence--the friend could be pulling the poster's leg, or Kathy could be pulling her friend's leg. Either way, I just don't see Kathy taking the risk by telling anyone a definitive date as to her booting. (Of course, Tom's 4th place finish spoiler did come from a family member, so some people aren't too careful).

The Oceanus spoiler is certainly questionable as has been discussed here before. Room #s, dates, likelihood of two bootees being housed on the same boat, particularly in the last non-jury/first jury boot slots. It seems much more plausible to be the first two jury boots, but it all sounds kinda fishy.

Gina's comments on Rob from the Early Show:
"A little stupid on the island but a great person. He's -- you know, it's the way he played the game. I just -- I think he could have strategized a lot better and things could have been a lot differently if he would have made one, you know, crucial decision early in the game and he didn't. He chose to go another way and even talked about it and I think that was a stupid decision on his part, but he still is in the game and I'm not so I guess he's smarter than I am."

I guess all of the hubbub over this came as a result of the general tone of how she spoke of Rob, and people heard things that weren't really there ("outside the game" "He'll even tell you that.") But it does seem like Gina had time to get to know Rob outside the game--I doubt that they'd have enough time at the wrap party for Gina to think that Rob's a "great person", and after watching him on the show I don't think she would be praising him based on what she saw. BUT--it could be misdirection, or Gina could have kept in contact with him after the show. I just don't see them making that much of an effort to get to know each other once they got back from the island, so the only thing that makes sense is that Rob spent time with Gina at the Loser Lodge.
