Former Georgia Congressman Hopes To Scoop Up Ron Paul's Internet-Driven Support, Wired.

Nevertheless, Barr is is setting up the infrastructure to try to siphon off some of that Paulite passion.

He's hired Terra Eclipse, a Santa Cruz, California-based web design and consulting shop that designed the Paul campaign web site. And in an April appearance on Fox News, Barr pointed to Ron Paul's support base as a reason for his confidence that he'll find enough money to finance a sustainable campaign.

"There is a large body of folks out there that fall into the independent movement in the center," he said during that interview. "[There are] a lot of young people who are willing to give in large numbers small, reasonable amounts of money to support a true independent voice and choice."

Why Yelp Works, NY Times.

But Yelp has thrived. In March, it had 3.3 million users, according to Comscore, up 87 percent from a year ago. Citysearch still towers above it with 16.2 million users.

What Yelp did differently than these others, as Jeremy Stoppelman, the site’s co-founder and chief executive describes it, was to spend most of its energy attracting a small group of fanatic reviewers. It didn’t try to pay for reviews, as some sites have. It didn’t subordinate the users’ contributions to professional reviews, as on Citysearch, or to directory information, as on yellow-pages sites.

Instead, it structured the site to motivate people through the praise and attention that their reviews receive from others. “Yelp is about the reviewing experience,” Mr. Stoppelman said. “It is like a blog with a little bit of structure.”
