It really depends on the context and situation. One example off the top of my mind - I was working from some coffee shop, at the table next to me another geek was also coding. He seemed to be working on something interesting. After a couple of hours I just struck a conversation. We had lots in common in terms of coding areas of interest, shared some fun battle stories, etc. Eventually went back to coding and then went our separate ways. But it was a fun little interaction that I still remember, while for the life of me I can't remember what I was working on.
