This week I visited the corporate headquarters of Me.dium in Boulder, Colorado, and spoke with Dean Steadman, left, community management director, and Tobias Peggs, business development director. This startup is in beta, available by invitation . It adds a window to your browser that shows who else is visiting sites you might be interested in, and where you can follow them and chat online. I loved the high energy of their funky offices, filled with bicycles and more than 25 (to me) very young employees. When I suggested a photo, Dean and Tobias left the conference room to don company T-shirts, a spontaneous bit of corporate enthusiasm and pride that I never saw when I worked for a natural gas utility. Me.dium is a potent evolutionary advance for browsing the internet. When the Twitter buzz dies down, I can imagine an even bigger phenomenon: people realizing they don't have to browse the internet alone anymore. If as many people cross over as Dean and Tobias and their gang hope, one day in the foreseeable future it may well be all about Me.dium.
