We, especially the early G+ adopters, are very excited that you are here and want to hear from you a lot more! You are, after all, THE foodie of foodies!
One suggestion from a lowly "circler": CHANGE THE PHOTO! It's really funny and cute but whenever I see it, I feel I'm talking to Wilford Brimley ("Quaker Oats, it's the right thing to do"). Many people who are just signing on may know your face (e.g., the one between the melons!) but not necessarily realize that the guy in this photo is you! Guaranteed that if you do, your G+ following will dramatically increase.
And, not for nothing, but I also just checked your FB page - you seem to have put a lot more energy into your profile and posts there! As the saying goes, the more you put in...
Don't give up on G+ so quickly - you'll see that this is an eager and intelligent crowd!
