I have recently participated as a speaker at several press events: a traditional press conference with newspaper reporters; a recorded over-the-telephone radio interview; and a call-in event for bloggers. While my role was to provide background on higher profile guests, it was educational this time around to be a speaker rather than an organizer.
The topic was similar in all cases -- specific cases of entrepreneurship and environmental action around the world. The results, and in particular the online results, have been interestingly distinct.
