Yeah, pretty weak arguments there. Somehow what some people claim or have said is supposed to apply to me? I don't know about others complaining about ribbon on office, but I loved it when it launched, and I loved every Facebook iteration except the last one. I'm an early adopter, and not only does stuff I adopt early have an incredibly high success rate, but there aren't many things that are successful that I don't…
Wrt the UI - I disagree that the ribbon is a great UI paradigm. I can't imagine using the ribbon on a touch screen, looks far too fiddly!
