Okay, I've been looking into this some more. This morning I re-enabled jetpack on http://www.robdiaz2.com. I then logged out of wordpress. When I navigated to the site as a visitor would, I did not get the only secure content warning.
Upon logging in, I got the warning again.
So, it would seem that this has *something* to do with the iFrame involved with the WP login/admin bar.
I determined this by looking in IE's developer tools application and finding the https iFrame that was loading http content.
Not sure if this means the problem is really "not an issue" for most users, but it is certainly a major nuisance for those of us admining sites that use this tool.
Hope this helps you.
