Twitter and facebook both have tools that you can adjust on your smartphones that let people state the location that they are posting from.
So what’s the use? Simple. Morville discusses this in his book. By making themselves accessible, people are able to locate them more effectively. For example, if you used the smart phone “check-in” tool at the mall and one of their friends was at the mall too. Their friend would then possibly locate them or be able to connect with them. However, if neither of them knew they were there, they might not ever connect.
