“Twitterative Design”
Jakob Nielsen recently ran a Twitter post through 5 rounds of iterative design to get the impact he wanted. At first blush I was thinking, “That sounds like a lot of effort to optimize a Tweet!” But if you are using twitter as a marketing medium, I guess it makes sense. (Far as I can tell, these were just design rounds; he wasn’t running a user study or anything.)
See his article for lessons learned in each round, from concision to focus, impact, and re-tweetability. (There, I’m making up new words right and left.)
He finishes the article with a notable quote: “Text is a UI. It’s a common mistake to think that only full-fledged graphical user interfaces count as interaction design and deserve usability attention. ... In fact, the shorter it is, the more important it is to design text for usability.”
