I'll chime in a couple of months too late on one score and add it to your point, Polly - if someone is going to make softcore out of Alton Brown, I. AM. SO. THERE. Fortunately, GameBoy thinks it's cute the way I fawn over AB - I coo and sigh and swoon and bounce every time I watch Good Eats, and I was over the MOON when FoA was on. I loved him scruffy, I love that he motorcycles properly, I love his nerdiness...oh man. I could go on.
I've forgotten about this thread for a while, so I'm glad I looked in. I can't say for sure if they're going for a porn angle (heh), exactly, but then I think cooking is all around pretty sexy - when it's done well. So absolutely - food, visual stimulation, and hot hosts may very well equate to porn. I think I'm OK with that.
I do think quite a few of them - in addition to Alton - are tres sexy: Tyler Florence (who they don't show nearly enough of anymore), Paula, Paula's bigger boy (is that Jamie?). Giada does nothing for me - GB earned major points with me the day he declared that she looks like a bobblehead because she's too skinny! And truly...AB and Tyler may have a bit of squishy going on...but you know what they say: never trust a skinny cook.
(Um, no offense to any slender gourmets hanging out in here...
