If the show was edited better, these people would be remembered more.
As an avid Survivor fan, I have to disagree.
The reason people who don't make it far in the game are ignored, by the editors, in promos, and at the reunion, is because they weren't very important to the game. The editing purposefully zeroes in on people who drive the plot of the show, and those are often people who either make it far or at least have some kind of influence on tribal council.
Sure, there are sometimes early "characters" who get some screen time before being voted off in the pre-merge period of the game. Tall Kathy sticks out in my mind. But again, that's because she contributed some plot to the show (and the editors are working to create story arcs within episodes and throughout the season). She was awkward, and outcast, and struggled, and then she quit.
Compare that to, say, Spencer from Tocantines. Some people feel that Spencer was given short shrift and that he had a story to tell, as the youngest Survivor ever and with regards to his sexual orientation. And hey, perhaps there's a real drama lurking in the cutting room floor that we missed out on. But the truth is, Spencer is far from the first homosexual contestant on the show, and he also isn't the first gay man to downplay his sexuality for game purposes. Also, the main take-away of Spencer's youth seemed to be that a very young player may not make for a very good player. He was low key, wasn't much of a power player socially, and wasn't that great in challenges. He's a classic example of a pre-merge boot -- not that interesting, not that competitive, not that influential.
I understand what it's like to develop affection for certain contestants early on and then be frustrated when they're eliminated early. I was a big Michelle fan during the Fiji season, and was really disappointed when she was eliminated (particularly because it was truly due to some very bad luck). But that's the way the game works, and when the show focused mainly on players who made it farther than Michelle (Yau, Earl, Dreamz), I didn't mind.
The editors do a lot to shape the show, sometimes for better, sometimes for worse. But I just can't get on board with the idea that the editors should go out of their way to highlight (in a favorable way) competitors who are eliminated early. By the end of the season, I want to have a really good idea of who the remaining competitors are and how their games and alliances have evolved. That means ignoring some of the early folks.
