You are not from "everywhere", "the world", "the globe", or "the web". You are a human with your feet planted somewhere on the earth that influences your view of the world, your business, and your society. So tell us where it is so we can get to know you better.
Whenever someone new connects with me on a social network I check out their profile to find out if they are a real person, and a few other characteristics I have mentioned in earlier posts. And one of those key characteristics is a person's location. More than almost any other profile element, location gives me context for that person. And when a new connection doesn't tell me where they are or where they've been it significantly lowers the likelihood that I will add them to my list of people I want to listen to.
We All Care About Place
Where we live and where we have lived in the past influences how we see the world as much, in my opinion, as our education and work history. I know that every city I have lived in has had a significant influence on me, both while I was living there and after I left (that's one of the reasons why I love the "places I have lived" section of the Google+ profile). Think about the top 5 questions you ask someone new that you meet at a trade show, webinar or when you're away on vacation. I'm willing to bet that "where are you from?" is on that list.
So it's best not to be coy or cute about where you live and just tell us. It doesn't have to be a street address or your detailed latitude and longitude coordinates (The long code after "UT" that very precise people use). Just your neighbourhood, city, state, or region. Something that gives the people you want to connect with you a sense of where you are in the world so we know a little more of who you are so we can get to know you better.
How do you feel about sharing your location? Is there a reason why you are ambiguous that overrides a potential friend's need to get to know you a bit better?
