This is not necessarily true. I've lived in 4 different US states in the past 6 years. Status updates for a period can be enough to keep that relationship going to the point that if I called them tomorrow it would not be a 2 hour conversation around catching up so much as "Hey, I have a 4 hour layover passing through Las Vegas on my way to Chicago next week, want to try to grab lunch?" or "Saw you were going to a convention in LA, I live about 90 minutes from there, think you'll have time to grab a beer?"
There are many friends who I simply do not have the time to keep up with because they are not good about using their e-mail or social media resources. I simply cannot coordinate calls when I am three time zones away and work two jobs the same way I can send you an e-mail or facebook message (effectively an e-mail) or comment on a post you made while my code is compiling.
Without these tools, I'd loose track of friends I have had and miss opportunities to enjoy their company, pursue business ventures, get information, or other things in meatspace.
Good day to avoid cops. Crawl to work.
