It’s (not) funny, because it’s true.
I think social insecurity applies to most of us at some level. However, we geeks have the advantage that it’s pretty much expected. We can talk about it and joke about it with geeks and non-geeks alike. We interpret things literally, boy geeks suck at talking to girls, girl geeks suck at talking to boys — you know how it goes.
Suddenly, consciously or not, Facebook is a game to me: to perform my best in the social world I want to optimise quality of posts against frequency of posts. How do I tell if a post is good quality? I see how many comments I get and how many Likes I get.
