With use cases in chat, advertising and photo sharing, the Face.com API now estimates the age of the faces it finds in photos. The service released mood detection last July and has seen the number of developers registered on its platform double in less than a year. The age estimation is hardly perfect, but gives a guideline that joins a number of attributes the service can return from just a snapshot.
You may remember the full featured, unpublished API from popular mobile photo sharing site Instagram that we covered last month.

At the same time, it announced a beta public API would be coming soon.
For most of ProgrammableWeb's nearly six years, there were two things that always remained true about the mashup directory. First, that Google Maps is the most popular API used to create mashups. And second, that Flickr is a distant second, but well ahead of third. Recently one of these is no longer true, as the Twitter API has passed Flickr in popularity.
