Discovery would be better served by having someone that actually cares about the environment narrate their show. Sarah Palin is anything but pro-environment and a mere profiteer. While her celebrity might boost ratings initially, I suspect that after that peak Discovery will find ratings taking a sharp dive. I've always had respect for the Discovery Channel until now.

Not a fan. The only thing I would watch with her involved is a trial.

"It is interesting how she wants the media to leave her family alone but has no problems parading them in front of the camera for her own ends." More than a little unfair since you admit you don't even know what format the show will take. Also, isn't that what Bill & Hillary did with Chelsea? She was off limits until they needed her to walk between them holding hands after Bill's mea culpa about Lewinsky? Typical double standard.

I guess it would be good for Alaska tourism,
as long as she doesn't cut out and leave in the middle of the show.

No.
