Twitter API

September 11, 2007

From Read/Write’s interview with Twitter co-founder Biz Stone

Biz Stone: Yeah. The API has been arguably the most important, or maybe even inarguably, the most important thing we’ve done with Twitter. It has allowed us, first of all, to keep the service very simple and create a simple API so that developers can build on top of our infrastructure and come up with ideas that are way better than our ideas, and build things like Twitterrific, which is just a beautiful elegant way to use Twitter that we wouldn’t have been able to get to, being a very small team.So, the API which has easily 10 times more traffic than the website, has been really very important to us. We’ve seen some amazing work built on top of it from tiny little mobile applications like an SMS timer that just allows you to set a reminder over SMS to call your mom or something like that, to more elaborate visual recreations of Twitter like twittervision.com which shows an animated map of the world and what everyone’s doing around the world with Twitter. Twitter is popping up from Spain and Japan and United States.And that’s very, sort of like, “Look at that!” It’s like staring at a fish bowl or something – an aquarium. You just find yourself getting lost in it. The API has really been a big success for us, and it’s something that we want to continue to focus our efforts on, looking forward.

Luke Wroblewski has been doing some research for his new book, Web Form Design Best Practices, through actual usage data. To that end, he has been working with Etre on several eye-tracking and usability studies focused on specific aspects of Web form design.

You can read more about here. What I did find interesting about the research was that form B (shown below) had the least fixations and the best visual distinction, while still giving equal weight to the primary and secondary actions.

Form B

As expected Form E did the worst of the lot.

“…Only Option E performed poorly during our testing. Six people mistakenly clicked on the “Cancel” button when attempting the task with this design, while many more lingered over it before realizing that they were about to make a mistake. People, as a whole, were around six seconds slower when using this design than they were when using Option B (a considerable gap when you consider that the placement of the buttons was the only thing that differed between the two). They also required a higher than average number of fixations to complete the task (with a higher than average total fixation length and average fixation length)…”

Form F

Which pretty much tells me that we should be forms the way we always have.
