I would say both men, and women can do a great job hosting talk shows. It just depends on who it is. Which talk show were you watching?
In my opinion I like Conan O' Briens talk show he is so funny, and now that he's on TBS he has a team of new writers.
As for a female talk show host I can't say I like a single one except The View. The only reason I like the view is, because Whoopi Goldberg is awesome, and I like what she has to say she is a really down to earth person. The other hosts I don't care much for especially Hasselbeck's wife.
