"But then, I don't imagine you, Josh, were very forthcoming in sparking conversation with them either."

I offered banana chips to a complete stranger. They ignored me completely (and I know they heard me). That was your last chance, society.

At this point, I have to just acknowledge and own the awkward, and move on. I'm normal enough to recognize it, and geek enough to only be able to do so much. However, it did occur to me this morning that it might be interesting to have a "Looking for Group" section at such a con, where people hold up whiteboards with something like "ALASKA" or "GRIM FANDANGO" or some other short word or phrase. These groups wouldn't necessarily have to be besties afterward, but it might be an interesting thing if you were solo-ing and were looking for somebody to talk to while standing in line. Geeks can talk to each other, we just need a driving purpose to filter the infinite. Also, it'd be... replicating the... LFG areas in... WoW, and other MMOs...
