Last week I scribbled about the future of the social health community. This week I’m in Australia speaking about screaming babies. Practical parenting, social media. Such divergent things.

At SXSW I listened to author Tim Sanders suggest we all need to stick to just one thing otherwise folks will be confused about who we are – our brand will get fuzzy.

I’m not sure.

While a niche is important, it’s not everything. Case in point: Steven B. Johnson, one of this generation’s most talented nonfiction authors. By day he oversees his social startup outside.in; by night he travels the globe speaking about his bestselling books, among them Ghostmaps, and The Invention of Air. In his free time you’ll find him writing cover features for Time Magazine on topics like Twitter.

And then there’s Daniel Pink, former speechwriter for Al Gore and peripatetic bestselling author, speaker, thinker. Manga, motivation, videos on travel tips. Nothing is outside his realm, it seems.

Two remarkable people defined more by their curiosity and thinking than the imposed confines of a tangible niche. And it works.

I’m guessing that Johnson and Pink don’t spend a lot of time fashioning their look. They just do … and they do it well.

Perhaps that’s how I think I’d like to be seen.
