Discussing this site with a client as we prepare to recast his navigation system. This is certainly navigation you will not ignore.
One of the problems I have with the all-verb style is that, with so many directives in a row, it starts to feel quite bossy.
YOU WILL OBEY MY EVERY COMMAND!
EAT YOUR DINNER!
Strikes me as a funny meme: the notion that nav must always be all verbs or all nouns. I get the logic but, when it comes implementing a design in the real world, you get bent out of shape fast, compromising clarity for the sake of consistency.
Reminds me Churchill’s alleged retort to a fussy editor when sent a note about ending sentences with prepositions: “This is the kind of nonsense up with which I will not put!”
When it comes to labels, it’s valid to worry about the cognitive dissonance between an action a user can take (donate, search) and simply directing the user to an information page (news, events). But designers and clients can get hung up on this. No need. It’s not like some nav elements are in English and some are in Chinese. Relax.
Weighing it up, go with the helpful label rather than worry too much about the purity of the cognitive experience.
