When you think about social media you probably think of Facebook and Twitter and maybe a handful of other major service providers.
What all of these services deliver is the ability to form relationships with either individuals or groups on a global, that is, Internet-wide basis.
This global orientation is important as these services only support being part of a geographic locality through the groups you join and even then they aren’t actually focussed on where you live and the people who live around you.
Now, when you consider the nature of modern life there’s something that is generally agreed to have diminished over the last few decades: Community.
Think about it … do you know all of your neighbors? Do you have a neighborhood watch? Do you know whether there have been break-ins or thefts in your neighborhood?
