Fast Company Names Blip.tv's Dina Kaplan and Arianna Huffington as Most Influential Women in Web 2.0

What to learn from her: Don't always take a medium's so-called limitations at face value. In Huffington's able hand, blogs became primary news sources -- not merely sources of commentary. And aim to conquer your doubts. "Fearlessness is not the absence of fear, it's the mastery of fear," she says. “Overcoming fear is, I think, the most important lesson in terms of achieving success.”

What she's done: Kaplan is the co-founder and COO of blip.tv, a platform for producers to distribute original shows on the Web. Blip.tv was the initial platform for Wall Strip video blog, which was bought by CBS for $5 million last May. Under its model, producers don’t need Nielsen to know how their audience feels—viewers of shows delivered via blip.tv can comment, favorite, and share content.

How she got there: A graduate of Wesleyan College with a degree in economics, government, philosophy and history, Kaplan worked a couple of jobs in the White House before landing a job as an Associate Producer for MTV news. She later went on to work as a TV reporter for NBC, before finally being recruited to join the team that started blip.tv.

What to learn from her: If you're trying to launch a new venture or just get noticed, Kaplan thinks the best thing you can do is just listen. "Listening is way more valuable than talking. When blip.tv first launched, we learned this the hard way. We got no users for the first month." When you do talk, "ask questions, ask what problem do you have that we could solve? What's missing?" This way you can find a viable niche and make your mark, or a void and fill it.
