There are tons of projects (even some open source projects) investing heavily into AB testing and other usability testing. Unfortunately, nobody ever seems to publish the data from these studies. To really move user interface forward, it would be great to have a large list of UI design tips that are backed by real world data. Do X and not Y : 72% of users found X easier. Nearly everything I read about UI design these days seems to come down entirely to the authors opinion. Surely there is a better way?
