I'll have to agree with the first poster about David Celdran.
He's smart, well-spoken and pleasant.
I also like the um, old lady (sorry! I swear I can't remember) who hosts the travel show on Studio 23. I like the fact that she's adventurous and eager to learn about where she is.
Lalaine (the kid from Lizzie Maguire) on the Channel 99 segment she hosts. I was prepared to think that she'd be a little obnoxious but after watching her I thought she was pretty game about the whole thing and she's very charismatic too. I'm a fan now.

The kids from Goin' Bulilit - okay so a lot of the jokes are corny but going past that I can see that a lot of these kids are actually smarter than they look. The kid (for one) who plays Korina Kanchez really seems astute and aware of what she's saying more than some adult personalities who don't process what they're reading off idiot boards.
I used to like Donita Rose but she's not on tv now.
Internationally I'm very partial to Ellen because she's got energy, charisma, is extremely pleasant and she doesn't have to 'gay' it up while at the same time being open about who she is. --On the other hand Rosie O' Donnell turns everything into a personal comment against her OR political attack (let's not forget the Clay Aiken thing and her fight with Hasselbeck. You may not agree with her politics but you have to be respectful.) Props for being unwavering but there has to be some sort of compromise.
I also like Conan O' Brien, Amy Poehler and Tina Fey.
