The food network needs another hectic life guru. Rachael has moved to greener pastures. Melissa is a mom too, that will only build on the number of people who can relate to her.
I think sometimes these type of stars become so wealthy and achieve such celebrity status they eventually out grow their audience. Martha Stewart was that way to a certain extent, but I think she has always been wealthy, it's just that now she is off the charts.
Once it is such a distant memory for them of what life is like for the everyday viewer, I think they struggle a little to keep on that level. Especially if the economy becomes dismal for many and they have never lived thru something like that, and are at a level now they don't even feel it the way most do.
Melissa may have just hit the market at the right time to start her climb though. Then in 5 or 10 years it will be someone new.
