Otis says a post on Mashable is what started his site’s explosive growth.

At Saturday’s Mashable party he told me how a Mashable blog post about his site, Goodreads, instantly generated a bunch of new registrations. Because goodreads already had its social components in place, those new users brought in other users and Goodreads kept growing.

I guess that’s why at parties there’s always a line of people trying to meet Mashable’s Pete Cashmore and Adam Hirsch.
