I think given the nature of the software and startup world it's not unlikely for people to meet each other. I'm pretty sure most people on HN will be connected to each within one-two degrees of separation. I know I'm connected with tptacek by one degree and linkedin tells me I'm connected to patrick within two degrees through two different people. Someone should write a six degrees of HN app :-)
