Very cool.

Thanks, Anubhav. In our UX process, we come up with a hypothesis — like greater friction leads to more sign-ups, to give an unlikely example — and then test it through usability testing. That is, we create the UX and test it qualitatively. But you’re right: in that example, we’d only be able to validate whether the design was usable, not whether there was a quantitative effect. That’d require us to ship it and run the numbers (which we also do).

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
