Emeril Live IS Emeril's presence on the Food Network. It's the 'BAM' that gets you there. It's the invitation of PS #Whatever's cooking class in to go over techniques recipes. It's having other Food Network chef's in the kitchen with him. I still remember the Batali/Legasse Emerial Live.
I watch occasional Essence of Emeril episodes because I love his recipes/flare on Live and am willing to lose the flair to learn the techniques, but it's not my bag. The specials? Similar feel. It's less meaningful to me to see him in a Food Network special if I'm not watching him on Food Network. He'll just be that guy in the special. (I know, that's not true, but I'm pissed that Emeril Live 'might' be done...)
Update
Looks like it's just Emeril not having an exclusive agreement with Food Network anymore.
My previous feelings stand.
