Apologies for the confusing experience today: as we mentioned when the Recent Photos module was removed a few weeks ago, we've been working on some optimizations and new styling for the right rail modules. A early stage of some of these updates was enabled by mistake today, and we are in the process of reverting those changes. It is not our intention to create mish-mash of styles.
