Kaila Colbin, ambassador for the Web Genome Project, writing “Google Watch” for Network World, talks about the virtues of building businesses upon businesses:

“Take, for example, Surf Canyon. Their handy browser add-on digs into Google results to pull relevant links from further down the SERPs — good for searchers, but also good for the sites, which would otherwise remain in ignominy.

Google should send a thank-you note to every one of its barnacles. They’re part of what makes the Big G what it is. And if you’ve got barnacles, make sure to appreciate them. They might not be good for boats, but they’re great for business.”
