One of the best tweets I’ve seen recently about web usability is simple and direct.
Like most things the simplest approach is usually the most effective. Tristan gets his message across in less than 140 characters and after reading it, we instantly get what he means. No further words are needed. That’s what Twitter has done really well, as has Tristan.
This rule can, and should be, applied to all websites if they’re to be used as intended; both internally and externally.
I have nothing to add. Do you?
