Our Favorite Adventurers on Twitter – Updated 9/2

Who better to follow in 140 characters or less than our favorite explorers? We've put together a roster of tweeters, from eco-activist David de Rothschild to alpinist Ed Viesturs, to keep an eye on the ever-changing world of adventure.

This list is by no means final, so keep checking back to see who's been added. And, as always, tell us who we left out in the comment section below. We're particularly interested in adding gear manufacturers, conservation groups, and outfitters that are tweeting, so if you're out there, let us know.

Of course, you can also follow us on Twitter at twitter.com/ngadventure

See the full list after the jump.
