It's true. One of the most frequent questions we get asked is "who cares if I'm at Starbucks anyway?"
Well, the answer is no one really.
Posting where you are: drinking coffee, buying clothes, drinking wine, eating lunch are called "vanity posts". Back in the day "vanity posts" were reserved for celibrities. I don't know why but some folks are interested where Johnny Depp and Sandra Bullock drink their caffeinated beverages.
For the rest of us well...
People reading your Social Network posts are interested in places where they can: drink coffee, buy clothes, drink wine, and eat lunch. So it's a service to let your readers know where you know they can find quality and value. So post away on places that you enjoy. Let your readers know that you think Della Fattoria is a great place to take your clients to lunch in Petaluma. Oh and post pictures of your lunch with a quick restaurant review.
Remember your posts are for your readers entertainment and information not to tell them how cool you are. Besides they should already know that.
