Although Foursquare is known for check-ins, the tips its users leave behind in the Explore search and discovery section of the app are rapidly becoming compelling assets for the startup. There are now more than 33 million user-generated tips, which is up 65% from last year – more than Yelp’s soon-to-be-released growth numbers. In addition, the tips on Foursquare are easier to parse as they are embedded seamlessly into its search engine. So although Yelp has reviews that are more curated, the mobile-centric platform lowers the barrier to entry for most users, and the shorter snippets of content seem to be more popular with a broader base of users.
