Yeah, I know exactly what you're talking about. There are plenty of people like that around here. I never really paid them much attention, though.
That's the main downside of it, definitely. There's one online friend that's in the same state as I am, and she's not that far away, so I may meet her sometime in the future. If all goes well, I may even be meeting another friend that lives further away. With my luck, that will probably never happen.
