I just met with Amanda Laucher at the Blue Moose Cafe in Morgantown, WV.
I don't live here; she doesn't live here; we weren't at a conference; we didn't expect to meet. We were both in town on family visits, and both seeking out an internet fix. (I'm visiting my father-in-law at Ruby Hospital - but writing Python there, hah.)
She's a serious geek-community addict like me - she's organizing the DevLink Bus. She gave me great advice for PyOhio and tipped me off to other upcoming events, and I gave her some ideas from PyCon. It was great!
That's just really cool. Someday, when wireless access is ubiquitous, geekish nomads will no longer concentrate themselves in a handful of WiFi hotspots, and unforeseeable meetings like these will become more rare. That will be the downside of the future.
