when a user comes across your Twitter handle or Facebook feed, she doesn't suddenly transform into a "professional-only" mode that consumes, filters and reacts to content based 100% on her company and career.
No, her professional persona may take center stage, but her entire thought process is also influenced by the less apparent parts of her personality: the fact that she's a parent, enjoys rock climbing, is coming off a rough week or lives in a city.
As marketers, we need to embrace this fundamental nature of user behavior; namely, that people act, engage, and respond not solely as professionals, but as nuanced human beings.
