Earlier this year, I took a leap into the future, and upgraded this blog to use a "Responsive" class template. There are four "Responsive" templates - Contempo, Soho, Emporio, and Notable. The differences between the four include more than merely the visible design.
We're seeing a number of reports from blog owners, claiming their blogs are now subject to security alerts - and blocked when sharing. Frequently, the reports involve blogs published to "blogspot.com" (not custom domains) - and using the "www" alias. Some services, such as FaceBook, are now requiring "https" for shared URLs - and the "www" alias of "blogspot.com" ("www.whatever.blogspot.com") can't be used, with the "https" protocol.
