Speechwriting is a notoriously solitary profession. You might have a few conversations with a client, their staff or — if you're writing for yourself — a mirror. But a lot of your work is going to be just you, a keyboard and the unforgiving blank screen.
At least, that used to be the case. But when you're crafting a social speech, speechwriting can be a team activity. And even though you still have to do the actual writing, you can draw on the ideas, experience and ingenuity of a large networked audience.
