I have been Fan GoH at various conventions back in the 1980s and 90s, culminating in Fan Guest of Honour at the Worldcon, but this is the first time I've been invited as a pro Guest, so that's pretty special to me. I had always dreamed of being a pro GoH, though back in the 80s I assumed that it would be as a writer, not an editor. (But apparently, you have to actually finish your novel to qualify as an author guest.... as I have admitted many times, editing a novel is a lot easier than writing one.)
I find it fascinating how many of the fans I did zines with back in the 80s have subsequently gone on to become pros. We were just kind of goofing around, but I can count four with published novels, two who became editors, and one who became a prominent book designer. I can't help wondering if Facebook or Twitter or Tumblr will produce the same % of next generation authors....
Anyway, excited but a little intimidated by the opportunity--Sally Harding's GoH speech at this year's WWC was wonderful: funny, insightful, and uplifting. Tough act to follow!
I'll do my best.
