Google and others have been pushing for HTTPS everywhere. If I recall, they put something out last year stating that having https will be factored into a site’s ranking. My web host has made it possible to have https on their hosted accounts as of this past week. For free! As in beer! So update your bookmarks to this super frequently updated site to use https because you can.
I had to fix a few things that caused mixed content warnings including finally updating the ancient widget that I was using to show my tweets over there on the right. It’s been broken ever since Twitter switched API versions from 1 to 1.1 and started requiring OAuth. It was going to take a bit more work to update that widget, so I opted for the one from Jetpack that uses the Twitter widget instead. I could configure that via the existing editors versus having to go grab a PHP OAuth library and having to figure out how to integrate that into WordPress.
