Firstly, people take social media waaay too seriously. They rely on it to feel connected and a social part of society. While at the same time studies are showing that social media is making us depressed as we now are able to compare ourselves to others 24/7 and feel like crap if our witty status didn't get as many likes as you would have hoped.
If you look at my own personal facebook page, the last thing I posted as a status was just hoping everyone was safe in the awful storm that recently hit my hometown and a large chunk of NSW. My facebook page has my workplaces, but not their whereabouts, a vague mention of my city "Newcastle" and my relationship status. Yes you can google me and find out things, but most of that you'll probably learn from my blog.
Ignoring the fact that I now use Facebook to promote Permanent Procrastination, I use it to keep in touch with friends. Friends by the rough definition of people I actually like and want to keep in contact with. People seem to have a hard time with Facebook, too many people can see their things, (change your privacy settings people!) unwanted comments on posts, (privacy settings again) and then people in real life who you either don't have on Facebook or potentially people who don't even have a Facebook, know what you're up to. Which is just downright creepy.
Now while I can't stop my elderly family members calling each other up and chatting about how I went to see some movie with my longterm partner and seemed to have a good time. (There's worse things that they could be rambling about) I can stop people that I seriously don't like or have no interest talking to from seeing any of my business.
Every now and then I like to scroll through my all of my Facebook friends and ask myself a simple question.
Would I smile and say hello to this person down the street?
It seems dumb but do you know how easy it is to accumulate people on Facebook that you would physically avoid if you saw them in person. Do you actually want those people to know anything about you at all? Because I don't. Screw those guys! People like that only want to know things about you so that they can talk about you to others in some sad jealous way most likely.
If I don't want to talk to these people in person I definitely don't care what's happening in their lives and could care less if they knew what was going on in mine. I have just over 220+ friends on Facebook and I don't think that your personal profile is a social media site where you should just be collecting people.
So to answer the opening question, If I don't (or wouldn't) talk to you in person then I don't want you on Facebook.
