He is a very talkative, hands-on person. And a wonderful magician. I like him, and he had enough personality as the host of this show.

I think it's okay as long as the contestant agrees and Penn's actions are restricted to hugs.
The show must have strict rules against "kiss and Teller".

he takes forever to reveal the persons identity, so slow

Penn is 6'6".

More unusual trivia: According to Wikipedia, Penn suffers from prosopagnosia, an inability to recognize faces. Odd that he'd be the one to host Identity, then.

I don't what it is, but for some reason producers keep casting hosts that practically molest contestants.

Take a look at Family Feud. Nearly all of the hosts of that have quite literally fondled the woman on the show; in fact one of the older hosts got in trouble for it.

Even recently, John O'Hurley keeps coming on to the old, ugly, and fat women and mauling their hands and squeezing them. He's trying to be nice to them because they are unattractive, but it's actually having the opposite effect; if anything it's insulting that he draws unwanted attention to them like that. You can clearly see that a lot of them are uncomfortable.

It's really getting annoying the way that hosts are so touchy-feely. Even when the hosts aren't the contestants are. Didn't that stupid woman know that Howie has OCD and doesn't even like shaking hands? Or, did she just think that she's so friggin' special that she gets to kiss! him?

I guess it's just the society we're in. Like everything else, sexual freedom has it's price.
