Yes, your favourite filmstar you follow isn't there. Yes, nor are 10 people you know. But you know what? nine million, nine hundred thousand, nine hundred and eighty-eight other people are there. If you're bored, why not reach out and say hello to every one of them? (not yourself: that would be wierd)
I had a brief period 3 decades ago where on some electronic fabric (I forget which) I was contacted by random coders in Peru, to try and help debug a problem. I have no idea who these guys were, but we established a basis to communicate for a while. I think thats a lot cooler than Justin Bieber's latest tattoo drop.
I think it's like "but is he the one" -the belief there is only one, only one group, only one fabric to talk to people, only one way, is .. well it's silly. There are lots of ways to talk to people.
