Instead of displaying daily active users for their applications, Facebook has steered in a direction that focuses on monthly active users. Through the daily active user count, a company called Adonomics was formed. Adonomics evaluates daily statistics on Facebook applications and then places dollar valuations on the application companies.
Application developers will most likely be able to view daily active users from internal Facebook metrics, but the daily active count will no longer available to the public. By hiding a daily active count, this should keep developers motivated to keep inventing applications. Sometimes it takes time for the Facebook community to accept a good application.
A developer told CNET that it will be nicer to have a 22,000 monthly stat next to his application information page than a 1,500.
