Years ago a friend and I hacked together iFvckedUp.org with the intention of focusing on videos of ourselves and other startup friends talking about the fvckups we made (or were currently making) at our startups. We learned that a) filming yourself was hard enough to begin with, but b)filming yourself talking about how you royally screwed up was even harder. So yeah, don't change to a video format :)
(though the storytelling/editing tools are better now, so maybe worth taking another crack at?)
Chad, interesting take! I can definitely see it being difficult to talk about failures on video - it's hard enough to deal with them, let alone write about them. I feel that the ease of editability (if that word exists?) of writing makes it easier though.
When you can revise what you want to say over and over (how many times did you hit backspace while writing that comment?), you can convey your thoughts exactly how you want them to be conveyed. It's more difficult and time consuming to do this with video, so the 'pain' (if you will) would last even longer.
