I had to post because I just got back from the store - where I bought ingredients to try a recipe I Googled after being intrigued by the photo a friend posted on FB ('haystack' cookies if you're curious).
Maybe Janice was confused because FB/FB users (and the rest of the internet) employ the word "share" - she took it too literally? Obviously proximity (to you/DH) is also a factor - she assumes more access than your FB friends who live farther away...hmmmmmm...
Nope I'm still going to cast my vote for "nutty".
I thought it was fairly obvious that FB posts, esp. photos, are more personal updates
(i.e. "Look at what's happening in my life / how I'm thinking/feeling"), and not personal invitations unless specifically stated (i.e. "I'm at a bar downtown - who's coming to party with me?" - and even that might be a joke).
I think the only thing about posting food pics that can be disappointing
(not expressly rude) is when there is no recipe or other source - seeing something yummy and expecting someone to make it for/give it to you is unrealistic, but seeing something yummy and not being able to find a way to make/get it for yourself is a real bummer.
Point of Interest: I was on a thread here last night that was talking about recipes and I noticed that any time someone mentioned a recipe they were, uh, "encouraged" to post said recipe. Because, really, bragging about heavenly brownies without telling us how to make them is just sadistic.
