Here’s Trevor Smith’s social map. Trevor says, “I may be a little different than a lot of people because I carve out large chunks of my day when I’m unattached to all social media. I find that alternating between casting a wide information net and focused work without interruption keeps me interested and connected with the world but still productive on more linear projects.”
Definitely interesting that Trevor is actually able to maintain a “linear” focus in a web world that’s anything but linear!
