The internet is not my social medium of choice, but I know it’s one of the preferred social mediums among many of the people I happen to know and like.
This site is a private social network for me to keep in contact with my friends. It’s the online equivalent of a private social event in the back room of a pub. If you already know me in person, then you know all this.
If you’re someone I don’t know already, then I might try you out for a while, but if it feels weird having a stranger present amongst my social circle then I may well ignore you. I just find it hard to be at ease socialising online, and I usually prefer to have some sort of personal real-life reference point to form the basis of my online interactions.
