X-Teamers support developer communities in a variety of ways: attending/speaking at conferences, blogging, contributing code/docs/issues on Github, StackOverflow answers, etc. Please share some ways you've contributed to open source communities. If you don’t have any experience with such things, tell us a little bit about your feelings on open source and its benefits.
