My friend Hubert has started compiling statistics of Alexa's top 1 million websites. Specifically, he's looking at their SSL/TLS settings and attempting to show trends in the world that is port 443.  He recently released his May numbers showing a slow but mostly improving security environment.  I'm hoping he'll be able to chart these trends in a way to make it easier for people to consume the data and be able to dynamically look for data that they are interested in.  I guess we'll have to wait and see what come about.  Until then I believe he'll continue to post his monthly numbers on the Fedora Security List.
