#1: Existing Open Source Conferences

Initially I simple googled "open source conferences" and started working through this list.

Then I found this page maintained by Jeffrey Osier-Mixon (http://www.jefro.net/), for which I'm extremely grateful:
http://jefro.wordpress.com/open-source-conferences/

Using these two resources then carefully poring over all the sites, I generated a short list. This list was based on the criteria:
~ had obvious contact details
~ had an open "vibe" (excluding something like this: http://e.ubmelectronics.com/armtechcon/)

Over the course of about 24 hours I contacted 22 conferences, and felt satisfied with the details publicly provided by another 11 (the best example being: http://opensource.com/colophon)
