Recently we also “unsuppressed” share, afaik and this has heavily increased noise as well, especially since it has magical hover behavior.
I never use Share … if I do I will use the “chain” link, I don’t need the fancy email/twitter thing ever.
I too feel like we should opt for “default simple” … power users can add noise.
So, by default, logged in get “Quote / Edit / AI” but they can fiddle with these options if they wish and construct the options they prefer via user prefs.
An alternative may be an intelligent ... implementation that stickys the last thing you used.
Last one, e for edit we should also add a keyboard shortcut I guess like the other 2 have?
