Changes are part of life. It's just that changes should be for good reason and justified as much as reasonable to those most affected. Ok, these changes are meant to accommodate increased mobile traffic. Fair enough and good to know. However, it would be both reasonable and good business practice to share with us clearly how the arrows, the edit billboard, the Reply/Post folder and other changes enhance the site for mobile users relative to how the site was before. Simply it's called transparency..
How do these changes, particularly the arrows, the edit billboard and the Reply/Post
folder (well most all of them really) serve anything more than being a waste of space.
Asking the questions as we have done I don't see it as either unreasonable or antagonistic. Fair and reasonable is all.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
