Since we're voicing personal tastes, I like the metaphor of growing one's business. Being self-employed and currently growing my business, it has special resonance for me. Il faut cultiver notre langue.

And while we're on it I also like the term psychobabble, finding it occassionally useful and liking its sound. Fakiness is a great neologism that has not found its groove yet: i.e., less than 1K ghits.
