davidventernet on "[Plugin: Jetpack by WordPress.com] JetPack Infinite-Scrolling Integration Issue"

The white space issue is caused by JetPack Sharing CSS (or it's automating position). The whitespace disappears when I tick "Disable CSS and JS" in the admin area. - I could like to keep this enabled. I will try to move the default JetPack sharing position from inside the post content div to below it, and I will report back here if that fixes the JetPack CSS is causing the post to stretch to the same width of the current sidebar div area.
