"Pulse produces a personalized and ever-changing list of recommendations based on where you are, the time of day and Loopt’s own data on where you and your friends have been. It shows editorial descriptions and reviews from the partner sites and averages the ratings a business has received. Pulse also factors in more subjective factors, like which places are particularly popular with Loopt users at a given moment. That will help Pulse come up with recommendations that a site like Google might not, said Sam Altman, a Loopt co-founder." - Graham Garland
