I used a random password generator (set to 'readable', because the survey asked for 'words' or some such). Why would you do anything else?

I was sorely tempted to use "squeamish ossifrage". But with more than a thousand regulars, many of whom are interested in computing trivia, I figure it's likely that someone else thought that would be clever.

I'm pretty sure mine was unique - I went into my Ruby interpreter, loaded the dictionary I'd been using for class projects and used "sample" twice.

Second that :)

I used a random number generator for mine. Not so much because I think someone else could claim my prize, but on general principles that it is the correct choice.
