Besides having the heads positioned in an opposing fashion there is little to nothing that's different about these two profiles.
- The new 'banner' image is fully replicated.
- Vitals directly below the profile pic.
- The tabbed options look and function similarly but there are different.
- Timeline style profile - industry standard.
- Positioning of the top right settings and account menu - industry standard.
- Position of logo on the top left - industry standard.
- Position of search field: this is an industry standard.
- Where Facebook has ads; Google+ has ominous white space.
- Google+ has profile style tabs; Facebook integrates that into an extra row on the profile.
- Google+ clearly displays the nav bar on the left hand side - industry standard.
Are we as humans that predictable that everything on the top of a web page should obey a certain order? Maybe, yes. Are we heading to a face off between these platforms? Yes. May other platforms out there be different and present differently? Yes. You be the judge of the majors by telling me - @kempedu - if you believe LinkedIn or Twitter are operating on the same user design principles for profile pages.
