At this point, ANY host is better than NO host. Last year's telecast was BORING!
Ellen was a great host the year the Emmys came after the 9/11 attacks. She later hosted again and didn't do as good of a film by a longshot.
It'll be interesting to see what she does at the Oscars.
As for the Tonys, I don't think Ellen would be a fit. First of all: I don't think she is too much of a theatre person. Secondly, she and her show is based in LA. Thirdly, at the Emmys and Oscars, she has more freedom to be a performer. At the Tonys, the host really only has an opporunity to shine in opening the show. There's no time for bits in between, such as Ellen coming out wearing the Swan Dress as she did at the Emmys.
I would love for Rosie to host. At least we'll be guaranteed a musical number. If not Rosie, I can see Martin Short doing it, even though I don't think he'd be as good as Rosie or Hugh Jackman.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
