I received my first byline today for my volunteer work on The Conversations Network. It was on the IT Conversations "channel" for Retooling Developers for Geospatial - Where 2005.
They have been publishing audio content from conferences, lectures, interviews, etc. for a couple years now; some of it is pretty interesting -- if you have an interest in the subject matter.
As a website editor I write the short description (for the front page) and the longer description here. Find and tailor the bios and put a picture together. That's about it, but they have some pretty high standards for form and content.
