Newsflash bro: meatspace is messy and relationships take work.
Your comment, it doesn't address anything I've said. I'm well aware that relationships take work and that is central to my point: sometimes that work isn't worth it.
Consider the "Grandma" in your life, the person you love to help set up their computer, come over to troubleshoot, etc. What a sweet lady.
Now imagine there are ten of these people in your life. Now imagine they start loving computers and tell you all about the cool new stuff they found, etc. Now imagine you have no other relation to them other than these conversations. And they love starting such conversations.
