Nice app and website, but I don't see the benefit of using a Chrome extension versus a normal browser web app. I understand that you can use it to find the phone number of a person on your current webpage, but I think it should be secondary to the web app.<p>Especially since you're targeting business users, you should create a polished webapp for them.<p>Also, I think many HN users would agree with me on the issue of privacy. In order to use the extension, I need to grant it permission to read and write data on all websites that I visit. Not saying you're evil, but this means (in theory) you could sell by browsing history, my interests, or even my data (again, not talking about you, but in general).
