Facebook, at an event today, expanded graph search from its original 100,000 beta testers to “hundreds of thousands” of users, and is trying to convince even more users to get on an early access waiting list. It’s accomplishing the latter via the former: when new people get access to the service, Facebook automatically generates a news feed story, and by clicking on the words “Graph Search” in this story, you can sign up for early access as well.
Facebook is clearly making a big push to rollout the new product that overlaps with many discovery services like Google Search and Yelp. Time will tell if users will actually embrace the new functionality that would make Facebook a powerful tool for finding merchants, content and more.
