Magpie – a person who collects things, especially things of little use or value, or a person who chatters idly.
Docent – a person who acts as a guide, typically on a voluntary basis.
The magpie flits from branch to branch, picking up shiny objects (the latest app) and sharing them randomly (G+ one day, Tumblr the next).
She has no routine writing schedule, and her audience/customers have no idea what to expect next.
She occasionally shares something brilliant, and then disappears for weeks at a time.
The docent has a clearly defined area of expertise.
She shows up on time, and is able to clearly teach her audience within her niche.
Her customers rely on her as a resource and trusted guide.
She leads her readers in an engaging conversation about the chosen subject.
Your Writing Style
If you want to build something of lasting value, consider yourself a docent, not a magpie.
Whether you’re writing for business or pleasure, there should be a thoughtful through-line in your work. Your audience will recognize you from a mile away if you do it correctly. Further, they will grow to rely on you. And trust is the foundation of every successful business relationship.
