The problem I have is Google is doing this A&#x2F;B testing on their public apps in the wild. I don&#x27;t know if I&#x27;m getting the best interface at this moment or am being a guinea pig for some experiment. And not only UI experiments. Remember when Facebook reordered timelines to measure the affect on the reader&#x27;s mood?<p>I think experiments should be done in controlled conditions with mock data and informed participants. When you then sell something to the public I expect it to be a finished and stable product. I can then build my workflow around your product and know that it won&#x27;t be made obsolete overnight because you applied some enhancement in a patch.<p>When Google used to explicitly mark their apps as &quot;beta&quot; we&#x27;d joke about them being in eternal beta mode. It really looks like that&#x27;s not a joke.
