State of Connectivity: http://bit.ly/1Ey5ze2 - very good read on trends and challenges of getting more people online... As +vint cerf frequently reminds us, more than half of the population still doesn't have internet access! And even for those that do, we still have a long way to go to make it cheap, fast, and useful.

Wondering if that site update (layout, performance, etc) resulted in a statistically significant outcome? You definitely want to check out this companion tool for Google Analytics...
This article walks you through GA Effect, a web application that helps you identify whether events happening on your Google Analytics data are statistically significant or just pure chance; in other words, it separates signal from noise. In this article you will learn how to use GA Effect and interpret the results.

HTTP/2 is already paying high dividends: http://bit.ly/1Ab4UgE - huge overhead reduction in number of TCP connections, and that's just the start! 

p.s. HTTP/2 all the things! :)

TLS is not mandatory for HTTP/2. But Chrome and Firefox will only implement HTTP/2 over TLS... apparently to avoid HTML hijacking by the various Comcast or ISPs that like to insert their advertisement
