Mobile at Scale

I&#x27;m going to geek out here for a minute at the fact that Facebook made a screenshot diffing tool for testing. I&#x27;ve been wanting to build that very thing for a long time, but every developer I&#x27;ve talked to about it looks at me like I&#x27;m crazy.<p>So, am I still crazy for thinking screenshot diffing might be an effective way to verify builds?

HTML5 is not effective at the moment, but as phones become more powerful. I think it will take over. The same way the web app took over from desktop apps when personal PCs and network bandwidth improved.

Seems like no one&#x27;s really struggling to scale mobile I suspect because 1) usage, although large, is less intense and 2) much less goes over the wire (usually just data, not pages).
